Solving Quadratic Inequalities
The basic procedure and one full example is shown!
In order to solve the quadratic inequality we first solve the corresponding quadratic equation and then take test points in between each of the roots of the quadratic expression. We then use those test values to determine where our quadratic inequality is satisfied.

I don't know if my teacher is trying to show off by making the whole process complicated, or she's just not that good at explaining stuff. But within this 7 minute video I was able to understand what took a whole 50 mins to explain, in just 7 mins! You sir, are a damn good teacher.
I know my professor was going on about some crazy ass table of signs, screw that lol
I didn’t do good on a quiz on this. So now I learned how to correctly solve this stuff
@@peterroberts7832 Yes yes yes exactly what even it that. It isn't even a table!
same problem with my teacher here...
Peter Roberts LOL IKR
Even I am now 60, I still try to study again the maths to prove my brain still works
Good on ya.

You've literally saved my entire VCE career. I will support your Patreon... as soon as I can make my own money, sorry. But for reals thanks
im currently pulling an all nighter studying for finals n u have noooo idea how much this helped. thank you :)
ha! tell your teacher to watch my vids before teaching : )
Lol! So true tho!
I was in preschool when you made this video, and now I'm taking Algebra 2 and this video saved me. Thanks man
Glad I could help!
This dude filmed this 12 years ago and I'm Watching it in 2020.
Lol Not just you
@@chuksbhtv5440 lol
Almost 2021...watching this now😂
I m watching this in 2021 RIP
watching in 2021
I know this video is old, but I really can't thank you enough for helping me and countless of others with this. My teacher had us plug in our values of x into the original equation... Your method is much easier to use and understand, especially for this quiz I have coming up!
OH DEAR LORD THANK YOU THANK YOU THANK YOU. MY PRE CAL TEACHER IS DOING IS FIRST TIME TEACHING PRE CAL AND HAS NO IDEA WHAT HE'S DOING. I LOVE UUUUUUUU
Legit stressing about a college algebra final I have tonight where this is the main thing thats stumped me. Khan Academy was way too complicated and I thought all hope was lost until I found this. Thank God! Bless this man pls
thank you for teaching me everything my teacher tried to tell the class over the span of the day in 7 minutes. Incredibly simple and answered every one of my questions with one example
perfect! glad i could help :)
We had this lazy teacher who doesn't teach much and this helped me a lot. 7 hours left before exams. You saved me!
well, 'always' is a strong condition in math. there are others ways to solve them, but making one side zero and going from there is a nice, straight-forward procedure that one can do
My teacher rushes through everything and teaches us material that we wont be tested on a week before the test. I'm grateful you post these simple and clear videos that help me work through the concepts and equations. Thank you very much !
Hey do you still do maths
DUDE im doin geometry this year and highschoool and your videos are kickass... you explain it sooo much better than teachers, takes teachers a week to explain it properly but you got down in nearly 8 minutes!!!! kickass dude
Wow... this shows how simple it could be taught in class by teachers .. watched this twice and figured it out quick and left clueless in class...Gonna pass this test👍🏽 THANKYOU !
starting my exams in 34 hours and this helped me a lot.... thanks a so much.
Good luck!
Me too
Me too, lmao.
Sml
Its amazing how much more I can understand this in under 8 minutes in your video, than in one and a half hours with my professor...
how did ur life turn out 9 years later?
@@jhonnie6778 how are you now?
2 years latee
this really helped! i got a 97 on the math test the next day! this is awesome!
Me being jealous of you 10 years later.
@@Jacob-wz7pm lmao me too
imagine if he actually replied
b ryyhhhh\
are you alive?
man you saved my life. Thanks so much for putting it into logical steps and explaining. Everyone else is horrible at explaining this, including my professor. Thanks again man.
This video has been an actual lifesaver, test tomorrow and you explained this way simpler than my teacher. Thanks!
loved it ...even my teacher complicated the whole process and this was way too good.......love from India!
Thanks man, teachers always seem to assume we already know most of the stuff and they don't explain it well, at least, that's what my experience has been like. Great vids.
Man i just saw your website.....and....well...one thing i want to say.....THANK YOU very very much!!!
TYSM 😭IT'S BEEN YEARSSS OF ALL KINDS OF TEACHERS TRYING TO EXPLAIN THIS TO ME WITH NO ONE BEING ABLE TO HELP BUT THIS TECHNIQUE HELPS SO MUCH!!
Glad i found this in 2020
Best and simplest explanation ever!
Thanks mate the time line was the problem i couldn't understand before watching your video because my teacher decided to teach us this while we do another test. We need more teachers like you man.
I'm 4 hours away from my major exam and this just saved my life. THANKS MAN!
I know this was a long time ago but did you pass?
You are
the first person make me understand math thanks
come back any time!
@@patrickjmt wow you even reply on your very old videos. You’re the best!
Patrick you are THE MAN!!!!
I srsly rely on you videos so much... If I don't understand something in class I just tell myself whatever I will go watch Patrick's video on this lesson xD
And when ever someone tells me that they are struggling in math I recommend your channel to them
Thank you so much for all your help =]
Bro you are awesome..... I was trying to understand intervals for almost a week this guy cleared it in minutes... Thank you
I have been having quite a lot of trouble with inequalities recently, having never been able to understand them, but you explained it so clearly, more so than the measly textbook i own. Now that i understand, i just wanted to say thanks! Your video was very helpful. :)
my book only explains the most difficult stuff so I understand that but flys through the less difficult bits which are more difficult cuz u have no clue wth is going on. This video cleared up everything. THX!
dude u rock im taking as edexcel gcse and we got that topic i searched many websites even my main book and couldn't understand it but u made it so easy thankzzz :D
You saved my life. I'm planning on using your tutorials for all my math homework from now on!
WOW just WOW !!!! i tried to understand this lesson for about 1 week with my teacher.. and it only took me 7 mins to understand this with a video? what kid of sorcery is this?
It's wizard
THANK YOU SO MUCH, I HAVE A QUIZ TOMORROW AND YOU SAVED MY LIFE!!!! I CANT THANK YOU MORE!!!!!!!
THANK YOU! You've taught me more in 8 minutes then I've learned at school in 4 weeks. No lie.
It Was my 90 Min lecture and I didn't understand but you nailed it in 7 Mins.
Thank u so much.. I'm from Brazil and I've a math test in two days and this helped me a lot! :)
Oh may ghad!!! Thank you so much! You explained it better than my math teacher haha! Now I can now answer my math project! Thanks a lot!!!!!
Thank you so much! This saved me, I have a midterm tomorrow and was so confused on what to do after factoring the inequality. This is so helpful.
This was so helpful! Thank you so much! It actually makes sense now. My teacher (my 11th grade math teacher) just lectures on math topics. He expects us to take notes on his words and shows us no examples.
even though this video is 14 years old, it still saved my ass doing my homework
My teacher has been teaching this for an entire week and I couldn’t understand any of it, I have a test tommorow. Pray for me.
Didu pass?
I hope you passed. Cheers :)
did u pass lols
Did you pass lol it’s been 3 years
3 years man.. updates? Did you pass??
it took my algebra 2 teacher a whole hour just to teach this and she confused me. u taught me in 7 min. goated
Thanks so much for this, I have a 43 in Math because of this and imaginary numbers. I applaud you sire.
Thanks HEEEEAPS for the help!
This video alone makes all the years of tutoring I had to go through look like nothing. Could have spent my time watching your videos instead letting my parents flush that money down the drain :/
I'm doing my summer math packet and I there are a lot of things I cant remember from pre-calculus last year.. These videos are a HUGE help! They're a lot easier than going through my old notes and they probably explain things a lot better too.
I think you're working now!
Patrick is my best tutor teacher on YT
Thanks dude you really helped me. I was not getting the concept of inequalities but you made me understand that.
hey thank you so much im studying for a graduation test and your videos help me out allot
How was it?
This helped me A LOT. Thank you for posting this. I am no longer lost!
Man thank you!!
I remember now. My professor did not explain it well!
Thank you for your thorough video!
thank u so much! i was getting worried for my exam in math this tuesday until i watched this..this really helped me a lot..now i will always check on your videos everytime i'm having math issues..thanks a lot man! thanks a lot! :D
was the test hard?
I was about to give up on my homework until I came across this video. The textbook couldn't even explain it clearly. Thanks a bunch!
wow! this cleared up ALL of the doubts I had, I completely understand it thanks to you! and I feel more prepared for my exam tomor. Thanks for your thorough explanation, much love from Trinidad and Tobago.
hey pat..... thanks so much for your videos, have a finals tommorow and they helped me alot. and you have really neat writing.
How did they go?
my coteacher said that he learned a lot from your videos, we're both a math teachers...gotta subscribe for this channel..thumbs up!
Simply simply wonderful,,,,,very clear to understand and WHY the steps are needed....Thank you.....
Xbrunk: I agree with you. I am from Canada and I am 15 and am learning this stuff. Academics are very low in USA
Thanks, It's good.
THIS IS SO HELPFUL THANK YOU YOU JUST SAVED MY MATH MARK
You are the fucking man. I've been watching your videos through last semster and this semester in college. You>>>>>>>other annoying videos>>>>>>>>>>>college profs
Also I usually don't comment on any videos but damn!! thanks.
i am an 8th grader and you have saved me from years of confusion
Finally! A simple n direct to the point math video! Thanks!
Thanks so much, my substitute teacher confused me so much during the lesson and this cleared everything up!! Thanks again :))
This video was really well made, very good explanations. Helped clarify little details my prof was not saying. THANK YOU!!!!
DAYUM, wish you taught my math class.
Real helpful stuff, Patrick.
Thank you in the first few minutes i learned more than did in class, may god bless u
@GreenScreenPunkGirl i am sure there is. typically i just use the quadratic formula if it does not factor easily, so you may check those out.
I am a student from 2020 when we are in a quarantine because of CoronaVirus. People are experiencing the new normal. As a student, we can't go to school to avoid the spreading of virus. Some of us are doing online classes and the other one is answering our modules. This video helps a lot of students, thank you
you are most welcome :)
Very clear demonstration! I missed a day of class and this caught me up!
This helped me a lot. I've been having trouble in math and was giving up for a while, but then I remembered about your videos. Thank you for posting this! I love your videos and how you explain it detailed yet short and simple ;D
I think I'll be stopping by here more often, my maths teacher sucks, this was so easy to understand :)
thankyouthankyouthankyouthankyouthankyou!! I missed a day in class and this totally caught me up. :)
im taking a online class and this has helped me sooo much.. THANK YOU VERY MUCH
Thank you so much! This helped me so much. You explained it so much better than other videos! Thanks!!!!!!
Thankyou very much, struggled slightly with this topic, you explained it very easily and examples were very easy to follow, thanks again!
I love the way you explain this!!!! So easy to understand. Thanks.
I'm almost in tears because I've been working at this all day and my teacher made it sound like brain surgery and everyone in my class seemed to understand this but I was like "WHAT?!?!" But it's so clear here!!! Thank you so much :) So what do I do if there are fractions in the inequalities?
The fact that majority of the comments are people thanking Patrick for teaching this in 7 minutes and understanding it whereas the teachers at school have been trying to teach this for about a week but the students don't understand tells a lot about the teaching methods used at school today...hmm...
(also thank you this helped me out too C: )
well, you can not blame the math teacher who earns $35,000 a year to be around 12 hours a day : )
glad that my vids helped you out! i am ALWAYS available (my videos at least!!)
Taking a college pre-calc class and I was able to understand this concept even though I always struggled. Thank you!
You helped me a lot Mr. Thank you so much. I am ready for my calculus exam.
you are amazing .... your videos helped me alot during my high school ... and now iam an engineering student and i am still watch your helpful and useful videos thnQ really ..
This helps so much!
I'm an audio/visual learner, it really helps to see a problem done, thank you man!
I've never understood those labels, how exactly are you meant to learn without audio or visual?
Ghost572 If you have weak discipline and a wandering mind you need people to show you and talk to you, because it entertains your senses more. It's not a negative thing, but it's typically a sign of no discipline. They *are* smart enough to do it on their own, but they can't focus. It's called passive learning; it's much easier and less involved, but usually not as effective, but it's not *0%* effective. It can be pretty good...
VikingII Sorry but that doesn't explain the lable that I'm an audio or visual learner? How else are you meant to learn? touch sensitive learning maybe? or smell learning.
Ghost572 Oh, it means watching videos and physical examples. Like watching people work problems out on a board or a more "fun" way, rather than simply reading text. The default is *reading text* and "audio" or "visual" are things like a movie or cartoon to show you how.-- At least as far as *i* can see. Every time someone says that, they usually want the more fun way.-- *however* I believe that the most effective teaching method is the *best* method. If text is too boring for human beings, why do we do it to ourselves? Unless we are specifically trying to build our discipline in doing tasks that we dislike. Which kind of seems perfect, since everybody hates their job, but they build up the resistance through the years of monotonous trash work that is public schools. That's one conspiracy theory anyway.
Patrick thank you so much I never understood this before but you made it look so simple.
@lolernie glad i was able to help you so quickly : )
Thank you for your help. This was very helpful. Keep this coming.
you saved my life, thank you. *student writing in less than two hours*
0:45 I used Δ=b^2-4ac
you have saved my igcse bottom thank you so much
Thanks for this. I have never done Quadratic Inequalities in all my years of math in High School
Thankyou sooo much you are a lot better than my math teacher!!!
Thanks man, I have been trying to get my head around this for weeks!!
did you figure it out yet?
Thanks Patrick. You are the best. I watch your videos and my doubts are cleared☺☺
Thank you so much. This really helped me revise for my math exam tomorrow. Liked and subscribed :)
I hope you entered the college you wanted
