This taught me more than my math teacher did tbh! Thank you :)
That happens a lot to me😂
I have math final test tomorrow and thank you for helping you are the best
Thanks this is helping me to create a test for a school assignment!
+BlockMasta Boooooo
Lol
Faisal Alhumayyd same dude
How did the test go?
I always relieved when I search for a video, and find that you have made one for what I am looking for. You always explain so well. Your videos are so helpful, they frequently save me 😅
😂😂😂😂
my teacher went over this for like a week and i didnt know what she was talking about and i watch this video for like seven minutes and i understand....YOUR AWESOME
Only needed 1 minute of this video to serve as a refresher and stayed for the whole thing! Thank you.
Hi i am a 10th grader i wanted to say thaank you. You made this simple for me to understand this. It would be awsome to have you as a teacher : )
THank you this really helped unlike my teachers explanation I have a test tomato and this really helped me find a easy way to do this.
i was going to say "o my gosh thank you" but someone else has already said it. so ditto! i am in my first year of college and takin precal. i forgot all about this. thanx for posting it. you explained it really well. great job
Thanks, unorthodox teaching seemingly. At least to me. You actually explain the language structure and rules. Capable at doing and explaining. 10\10
yea! it was made just for you : )
How old r u now.. l mean after 12 years🤣🤣🤣
i love you
nice clickbait loser
Lilly With A AR15 2 mins ago... now that’s rare
how does this guy have almost a million subs and no videos
My math teacher is a sick guy so I can’t even diss him but I goof off to much in class, this mans channel has singlehandedly gotten me this 92.
yep its the night before finals and I have no idea what I'm doing, luckily I found this video and it helped me out a ton! I now am slightly more confident that there will be no summer school for me
I now understand math. THANK YOU!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I keep a playlist for my math tutor, anytime I come across pats content its an automatic add for me. You're a savior, I'm taking you with me through all of undergrad. The future of education right here, the personal virtual tutor
I have a math final tomorrow and I only remember stuff for the test (allows me to never study except for finals) and your videos have been really helpful in remembering everything!
Thank god for this video my homework was asking what the discrimination was to the equation and i was confuse so i search it up and found this. so thank you very much it help me a lot :)
Thxs sooo much!! I have a test on this tomorrow!
Thank you so much sir Patrick it helped me a lot. :)
When you uploaded this video, I was in kindergarten, Now, I am in class 10 in India, and now I am watching it. Superb!
thx so much really helpful things to know before my test
Got sick at school and have to try and learn this on my own 😭
Thank you so much!! I missed class the day we learned it and I was so confused
@patrickJMT living in hk right now, and you made more sense than my chinese math teacher. thanks
happy to help!
Thanks for uploading this video help me on my homework that my teacher didn't cover in class.
you teach better than my teacher thx
Mrs.Lighty's class ROLL CALL!
thankyou so much! this really helped mee :)
I am so thankful for these videos, thank you so so much!
Thanks Patrick. This was a very helpful video. :)
cheers dude. that sorts out question 10 on this past paper im doing. im sure ill remember this stuff now. also if i have a question on this sort of maths would you be able to do a video on how to work it out because my teachers at school arnt all that good.
This is the first helpful math video I've seen. Thank you
thank u ur a life saver.... can really explain how right now in a hurry to get this on paper
oh, its you again. LOL i just watched your other tutorial about quad eq (completing the square) and i really understood it more. thanks!!! =)
Great videos, thanks for them! They'll be very useful during my A-Level course :)
Thanks! You explained it very easily to me.
Great video, you explained much better then my teacher
THIS is great thanks!!!!!!!!!!
Thank you. This helped me out a lot! :)
Thank you! This helped a lot!
Thank you. Once again you have saved the day.
Thank you so much for explanation but I have one question. Can we use factorization in the discriminate or does it always have to be quadratic formula?
@CutieJulie15 yep, that is correct.
@mubbu100 you use the b^2-4ac = 0, meaning that there would be only one real solution. Plug in 2 for a, K for b, and 3 for c. Then you'll notice that k^2 - 24 = 0. solve the equation, k^2 = 24; and k = plus or minus square root of 24.
your writing is awesome!
just done this today in lecture !!!
perfect! good luck on the exam!
Sir what happen if they c is a negative
@joethn -b over 2a is the axis of symmetry of the quadratic graph.
Why can't my maths teacher be like you?! 😭😭😭
Thank you very much! You have some very lucky students.
Thank you so much sir Patrick it helped me a lot.
Thanks :) .I understand you more than my teacher :'33
:D
yay math videos! haha
hey i was wondering if you had any videos about imaginary numbers? like when the discriminant is a negitive number. we were learning about in class and i was at a total loss haha. i looked for it, but couldn't find one :/
tests they take in england i think
Having A Test 2morrow :(
Your the real mvp
After watching and listening to all his tutorials now I feel in love with his voice ... ha ha ha.. Thanks!
great teacher
thx very much
oh my gosh-
Yay for this video
Thanks.
this video is great... you really help people like me :)
im just practicing ALGEBRA right now.. Keep up the good work and upload more and teach us some techniques for us to understand the TOPIC ^^
Very clear, thanks a lot!
oh Patrick, thank you for helping with my homework lmao.
dy/dx= +or- sqrt D
Fast way to solve any quadratic equation.
It turns it into a simple linear equation.
Thanks, this helped me.
When do you normally learn this? What age?
thankuuu you just saved ma add maths 😅
This video was so helpful thank you!!!
Thank you for explaining this in a video my teacher goes to fast.
nice videos :) all very helpful. and ure numbers are very neat btw :P good job. what grade do you teach?
Why did you multiply -12 times -12 at 5:40
Thanks this cleared up alot
Omg so helpful you are a god
very useful, thanks!
Can you help me make the quadratic equation using the just the values? Because I can't figure what variable to attach to which number. Thanks
are you god?
thank you very much that really helped. i have a pre public tomorrow and i hope i pass!!!!
Thanks really helpful
thanks! helped a lot!!!!!!!
Explained very well (y) i understand perfectly
You should have talked about i.
Thank you so much
Can you do Discriminant with 4 digits?
Thanks its our exam tomorrow
Find the set of values of K for which the equation
2x^2 + kx + 2 = 0 has no real roots
AND
find the range of values of K for which the equation
x^2 + 5x + k=0 has one or more real roots.
How do i tackle these types of question where it's not as straight foward as substituting the discriminant part of the equation?
bruh ur a legend
Perfect! Thanks
thank you thank you thank you!!!
What kind of math class do you teach? Algebra 2? Calculus?
then why do we use the -b+divide b2-4ac/2a
where do use 2a?
yaaay i understand..... im going to sub great vids
How would you solve problems using the discriminate though?
Thank you
@SpEEdHackEr101 no problem : )
Well, the descriminant helps with determining the real solutions, but how do you determine complex and repeated solutions?
You need to also explain how to find what TYPE of equation is it too
thank you so much helped alot ❤
I've seen the videos that he has for normal quadratic equations, and you'll find soultions that are like "x = (+/-)(1 (+/-) √-15) / 4".
hey for a function Fg(x)=x has two equal roots, what discriminant do you use and why??
surely if b^2 -4ac = 0 you get a repeated root, ie 2 roots of the same value
