he posted this vid on 2008.. but still the kids of 2014 are still learning from it.. thank you man for doing this and saving humanity LOL. i just cant believe how far a simple but good educational video can do, he did this without asking for anything in return.. thank you so much sir you're one of my favorite math youtube teachers
I like died understanding this lesson when our teacher diacussed it but when I watched this video, I was like... "Oh... So that was how it was done..." Thank you so much! 😭
@patrickJMT, this video is excellent for a few reasons. The set up in the beginning is extremely well done, you showed examples of different types of rational inequalities, and you described the general process of how we go about solving them before you even started your example. It felt like we were all on the same page before we got into the meat of the problem. Thank you so much.
my pleasure! glad to help! this is the same stuff i show people that i tutor, only i charge a lot of money to show it! : ) of course, the only problem is that you can not get any answers from a video when you ask them! good luck!
Thank you man thank you......10 years have passed since this video was uploaded and still in 2018 it helped me out soooo much ... Thanks for your efforts ...
I was sick so I didn't go to school. My friend told that we learned radional inequalities. My first thought was Patrick would have a video on that...and you do. Thanks! :)
the most flattering comment ever! however, once you mentioned babies, you lost me. typical guy, i guess. still, very nice of you. : ) a lovingly cooked meal is always most appreciated.
Thank God you made this video, your are the first person to explain that number line where it makes sense. Everyone else wants me to punch in the numbers and find the signs... very confusing. Thanks again.
well, you can always post questions on videos or through my youtube account. be warned though that i get about 100+ questions a day and after working 12 hour days myself, i usually do not get around to answering many of them!
Thank you so much!! My teacher was tryin to teach this and man were we lost. Your video was clear, detailed, and straight forward. Thanks again. By the way did I mention you have reali neat writing?
I got that -1 ,0 ,1 are not equal to or less than zero but infinity is . I have 2 questions 1)if -1,0,1 does not satisfy the equation then why do we just write them in solution set ,and if we write them then why 1 is opened with this bracket ? ' ] '
thanks man .your an awesome teacher. i just needed some review and thanks to you i think i get now just need to gather the willpower to acually do the homework
I have my Pre-Calc finals tomorrow! I got so used to just flying by math classes in elementary school and middle school and the first 2 years of high school have fucked me over because I got so used to not having to do my homework! Thanks so much man honestly when I search a math video on TH-cam I don't watch it unless it is yours! :D
Wait.... but for the last problem, why is it bad for the top part to equal to zero? Wouldnt that still make it true, since zero is equal to zero, and the sign says greater than or EQUAL to?
I have one question: I was always taught when you had an equation that has a "Greater or Equal to" sign you shaded in the dot, but on your second example you left it open meaning "Stricter Than", you explain it as being "undefined" how did you figure that out? Thanks so much in advance!
On that last problem, would you end up multiplying that x in the bottom denominator out? You have x(x+1); would x^2 +x be more difficult or not matter at all? I'm just wondering if there's a reason you didn't.
Hello sir, i have done lots of problems using both method of finding the associated equation then solving using this method then intervals where i have understand the intervals whether open or close but since using that method to bring fractions towards one side and then finding P(x)=0 and Q(x)=0 (those points) so here i didn't understand whether intervals would be open or close . Thanks : Regards Ahmed
can anyone tell me why you cant simplify the last fraction to just -1/x ? -1(x+1)/x(x+1) should equal -1/x right? (eliminate (x+1) on numerator & denominator)?
Hello, do you have a video with solving rational quadratic inequalities? Or is it the same strategy as in this video? Because Quadratic Rational inequalities will come on my test! Answers is much appreciated, thank you :)
wow this guy better teacher than my Pre Cala college professor. Made that much more understandable. My teacher, always skips steps in her head, which throws me off time to time.
Hi PatrickJMT! You are so helpful! I am pretty sure I understand your method. But when I type the inequalitity into a calculator the answer is different! PS do you never have an greater/less than and equal sign because the denominator is always 0?
@Brutal252 He didn't explain, but the reason 3 is not included is specifically because it is not in the domain of the f(x), I don't know why he didn't point that out. Am I right?
a 15 year video teaches me better than my teacher. Thanks!!
he posted this vid on 2008.. but still the kids of 2014 are still learning from it.. thank you man for doing this and saving humanity LOL.
i just cant believe how far a simple but good educational video can do, he did this without asking for anything in return..
thank you so much sir
you're one of my favorite math youtube teachers
It's 2k17 and I'm here, reviewing with this video... :D
Thanx
* 2018
continues in 18 too
still here
I like died understanding this lesson when our teacher diacussed it but when I watched this video, I was like... "Oh... So that was how it was done..." Thank you so much! 😭
oh my god same!

glad it helped! my hand writing is normally that of a first grader, but i try to keep it clear in the videos!
It's Oct 2020 and I find this video pretty helpful especially during this whole pandemic making it hard to learn math online!
my pleasure! glad to help! this is the same stuff i show people that i tutor, only i charge a lot of money to show it! : ) of course, the only problem is that you can not get any answers from a video when you ask them!
good luck!
Thank you man thank you......10 years have passed since this video was uploaded and still in 2018 it helped me out soooo much ... Thanks for your efforts ...
He teaches better than my math teacher...
+winderson guimaraes Lol I bet you that is why we are all here! My math teacher sucks!
winderson guimaraes same
Same dude
I was sick so I didn't go to school. My friend told that we learned radional inequalities. My first thought was Patrick would have a video on that...and you do. Thanks! :)
Patrick is the best math tutor on youtube!
You are the best math teacher on the internet! Your handwriting is clear and legible as well, keep it up! Definately Subscribed!
For the last rational inequalities' solution set - (-1,0) U [1, infinity)
@AWPNubDiesel come back whenever, i am always here!
youtube had a 10 minute limit before?
valarmorghulis sad days, also please rate this video 5 stars
the most flattering comment ever!
however, once you mentioned babies, you lost me. typical guy, i guess.
still, very nice of you. : ) a lovingly cooked meal is always most appreciated.
@dirt0jumping
couldn't agree more
you are an awesome teacher...learned more in 10mins than an hr of class
Thank God you made this video, your are the first person to explain that number line where it makes sense. Everyone else wants me to punch in the numbers and find the signs... very confusing. Thanks again.
Dude, you're a boss. I'm doing a test review atm and had no clue how to do these types of problems, now I can, and have more notes. Thanks.
well, you can always post questions on videos or through my youtube account. be warned though that i get about 100+ questions a day and after working 12 hour days myself, i usually do not get around to answering many of them!
Its 2020 and he posted this vid in 2008 and still we are learning from this❤
WoW, you are the best teacher I have ever had. Thank you, Thank you, Thank you, Thank you, Thank you ;)
now i can kick my math teacher ass , i love you
i've been watching you for a year now!!thank you so much for everything!!
Thank you so much!! My teacher was tryin to teach this and man were we lost. Your video was clear, detailed, and straight forward. Thanks again. By the way did I mention you have reali neat writing?
maker of this video is one of the greatest human beings
thanks
well you 're simply the best math teacher
Brilliantly stated! Excellent way of breaking down concepts into simple to understand terms.
I have a huge test tomorrow and this video has cleared up a hell of a lot of fog. This will help my University marks! THANKS MAN! You should teach!
Simple and straight to the point with a touch of clarity. Ever considered teaching as a profession?
For the last one I got X E (-1, 0) U [1, infinity). Who else got the same answer?
yeah you right, dude
That's what I found.
I got that -1 ,0 ,1 are not equal to or less than zero but infinity is .
I have 2 questions
1)if -1,0,1 does not satisfy the equation then why do we just write them in solution set ,and if we write them then why 1 is opened with this bracket ? ' ] '
I'm not in high school yet, but this video helped me understand this concept a little more, thank you!
@mundorff92 no problem!
@nouh220200 to determine which intervals of numbers work and which do not.
@nLoL2 i used to stand in front of a board and bore people, yes. not any more though.
Thank you so much, I needed that help so much; don't know how much this means to me..Thank you.
@AflakAttack good luck on the final!
really great directions clear and easy to understand- thanks for helping me with my midterm tomorrow man
You are amazing!! Thank you sooo much! I can actually pass my test on Monday lol, thanks to you. You were much more helpful than my teachers lol :)
WOW! This video really helped me learn this material :)
Glad it was helpful!
@lahirumc123 my pleasure, spread the word to your friends ; )
yep
glad i could help!
u r a genius my teacher which isnt actually a teacher couldn't explain it in this simple way
Thanks subbed :D
@roxxyroll3r i hope the test went well!
You are saving my grade. I have an A because of your tutorials.
aww yea! : )
wow you explain 100x better than my teacher and the textbook in 10 minutes. Thank you so much!
@goofguy316 thanks. glad i was able to make some sense out of it for you
@lavendretta you do the same thing
A great quick explanation, thanks!!!
You are a good tutor man
Thank you so much! I had trouble understanding this concept and you cleared like 99% of it so now i'm able to solve these!
Thanks, man, I never knew how my teacher got the inequalities after you figure out the x's, but your # line made things a lot easier.
@mbsimmer stand on the corner and ask for change. sometimes i go to the public library to freshen up and make a video while i am there.
no problem!
thanks man .your an awesome teacher. i just needed some review and thanks to you i think i get now just need to gather the willpower to acually do the homework
Thank you teacher its relly help 1/5/2019
I have my Pre-Calc finals tomorrow! I got so used to just flying by math classes in elementary school and middle school and the first 2 years of high school have fucked me over because I got so used to not having to do my homework! Thanks so much man honestly when I search a math video on TH-cam I don't watch it unless it is yours! :D
These are great videos. Thanks for taking the time to make them.
Your so much better than my precalculus teacher
@TheTrueSong you can not divide by zero
thank you sir! ☺
thank u
ur explanation is really great
Wait.... but for the last problem, why is it bad for the top part to equal to zero? Wouldnt that still make it true, since zero is equal to zero, and the sign says greater than or EQUAL to?
Thanks Mr.Pat!
THANK YOU SO MUCH THIS SAVED ME

These videos are great! I have a test tomorrow, and FINALLY understand this XD!
wow, sometimes i just don't get things in math, but you really something difficult looks so easy, and i finally understand how to do this.
Hello sir, i have done lots of problems using both method of finding the associated equation then solving using this method then intervals where i have understand the intervals whether open or close but since using that method to bring fractions towards one side and then finding P(x)=0 and Q(x)=0 (those points) so here i didn't understand whether intervals would be open or close . Thanks : Regards Ahmed
Thanks a lot!! U r a great teacher!!
could you write correct answer sir? I found (-1,0) U [1, infinity )
Thank you so much!
This helped a lot!
can anyone tell me why you cant simplify the last fraction to just -1/x ?
-1(x+1)/x(x+1) should equal -1/x right? (eliminate (x+1) on numerator & denominator)?
Hello, do you have a video with solving rational quadratic inequalities? Or is it the same strategy as in this video? Because Quadratic Rational inequalities will come on my test! Answers is much appreciated, thank you :)
Thank you so much. You are more of a teacher than my own teacher >
@patrickJMT what kind of books??? just wondering
thank you sir..you really helped
@karim7ahsan glad i do not have to grade everything : )
This video was posted in 2008. It’s November of 2017 now. Almost 10 years later and this video is still saving college algebra grades 😂
thanks! : )
wow this guy better teacher than my Pre Cala college professor. Made that much more understandable. My teacher, always skips steps in her head, which throws me off time to time.
God bless your soul. This was helpful!
@wolski888 What part of Canada are you from? I'm from Manitoba and we use Union. So, not just a U.S thing.
God bless you man!
Hi PatrickJMT! You are so helpful! I am pretty sure I understand your method. But when I type the inequalitity into a calculator the answer is different! PS do you never have an greater/less than and equal sign because the denominator is always 0?
That helped thanks !!!!
How did you know to test 5 for the intervals? Is it just any number?
I watched this at 2017. Thanks!
@spikeeleslie minus sign is meant to be a less than sign
@Brutal252
He didn't explain, but the reason 3 is not included is specifically because it is not in the domain of the f(x), I don't know why he didn't point that out. Am I right?
i can smell that sharpie....
thanks so much :) i have a test coming up soon, and you explained really well :)
@ 6:40 why is there a circle round 3 is it not...
...-4/x-3
Is union or "u" used in the US? because I'm from Canada and we use just "OR"
Im so glad I found you! You have saved my ass, thank you!
P.S You know there is a way to change the 10 minute video limit in your settings ;)
@ChowRamen duct tape and a stack of books
@rockangel7777 i have been here for about the past 2-3 years, i do not know about the rest of it!
