Thanks so much for this video! I know you don't get a lot of views, but I just want to tell you to keep doing what you're doing because you're helping thousands of students across the globe. Thank you for taking time out of your day everyday to make these awesome videos.
Thank you so much. I get so anxious and frustrated with math, and you have such a calming voice and move slowly enough for me to understand what is happening. Thank you so much. You are an AMAZING teacher!
Thanks man , now I can flex my skills in front of my female classmates , I tried to use this way to solve specific questions but my brain just didnot know what to do next , now I get it thanks .
Thank you so much for making this! It was a clear and simple way of understanding this method, and after being utterly confused by the other instruction videos made about completing the square, I have to say this is the easiest one to understand. It was great help!
Thank you so much for your effort to make it so simple and well explained. I graduated many years ago in Brazil, and now I'm studying on my own to graduate in the US and pursue a career. ❤

if you use scientific calculator then squareroot any negative number the answer will always be undefined, therefore the squareroot will always be positive
MR. Organic Chemistry Tutor ,thank you for an incredible video/lecture on How to Solve Quadratic Equations By Completing the Square. This is another Mathematical tool that students world wide must plant in their toolbox forever,
Multiply all terms by 3 to make the a value into a perfect square, then use c=(b/2)^2•(1/a) to complete the square. c=(24/2)^2•(1/9) c=12^2•(1/9) c=144•(1/9) c=16 3x^2-8x+5=0 9x^2-24x+15=0 9x^2-24x=-15 9x^2-24x+16=16-15 (3x-4)^2=1 |3x-4|=1 3x-4=1 3x=5 x=5/3 🏳️🌈 3x-4=-1 3x=3 x=1 🏳️🌈
For first problem you do not need 1 hour to follow useless way . Just instead 12x put 4x+8x and make 2 groups and start to factor . x*2+4x+8x+32=0 (x*2+4x)+(8x+32)=0 again factor x(x+4)+8(x+4)=0 again factor (x+4)(x+8)=0 if x+4=0 x=--4 and if x+8 = 0 x=--8 finish
yo don't trust this video it wrong. the problem at 5:17 is wrong. A negative divided by a positive is still a negative. which makes the whole problem wrong.

I just want to say that your videos are honestly the most helpful and easy to understand out of any other math tutorials. Thanks so much dude!
That's for sure 👍
I agree.

About that...
He gets a lot viewers,he is Chemist!
Thank you so much. I get so anxious and frustrated with math, and you have such a calming voice and move slowly enough for me to understand what is happening. Thank you so much. You are an AMAZING teacher!
Suddenly remember that I have a test tomorrow and now currently watching this at 4am, pray for me, this yt channel is a life saver.
Some people…like you…are born to teach algebra without confusing the heck out of us. Thank you!
Thanks man , now I can flex my skills in front of my female classmates , I tried to use this way to solve specific questions but my brain just didnot know what to do next , now I get it thanks .
Thank you so much for making this video! I was struggling on pre-calc, and now I am struggling a little less!
I like your videos , you are a super teacher. Happy new year.

I always understand maths better after watching your videos,thank you❤️!
I was Really bad at math.But now I 'm quite good at math cuz of ur organised vds.😍😍Thanks an ocean
Sir
Love this guys voice
Lol
He sounds like Lewis Hamilton.
Me too
Thanks for clearing my concept in 2 min I was struggling from a whole week
if you move a term from the left hand side across to the right hand side it changes sign, simple and a lot easier than youtubers show.
Thank you for showing the whole process clearly. That's what my college teacher needs.
Thanks! A good way of explaining things and very calming voice 👍
What a great help in learning how to complete the square!
I don't know how I can thank you. Thank you sooooo much.
Videos are easy to follow and easy to understand.
You make like doing these equations,and it's the way you solve it ! Thanks Doc!
this is old asf lol but this finally made me understand the method of completing the square, cheers mate :D
Trans half life 1 scientist

Minha sogra fez sopa de macaco, uma delicia!
Thx bro for the helpful information and its easy to understand🙂🙂🙂🙂
I um really so grateful....this is great..continue sir what u are doing .....❤❤❤

2:33 How can we factor the Expression on the left
7:13 A leading Coefficient that's not 1 and Common Denominators
10:21 3x Squared minus 8x plus 5 is Equal to 0
It is very instructive thanks to you
thank you so much you are a life saver
its great to see your growing channel. You deserve it!
Thank you for your wonderful explanation, it was a very helpful material for my test.
You the life saver
So powerful,we appreciate you alot✊
Thank you for this!
thanks for every video, I wanted to ask you what do you do when you have a negative
number in a square root in the complete the square method?
if you use scientific calculator then squareroot any negative number the answer will always be undefined, therefore the squareroot will always be positive

Where did 3 by over 3 come from on 12:39?
10/10 bro you saved me 😭
wait why didnt u square root the 4/3 to 2/3 at last problem?and thank you your vids are very helpful:)
Thanks for this video love it
Thank you so much.
Excellent
This saved me rbo thanks!
Thank youuu soo muchhhh❤❤❤
Your videos are sooo comprehensive
bro is a godsend
Hahahahaha another version “it’s just gonna be that way”,but I got it correct,tears roll down my face
Great video
Can you slove this 4x² + 6x - 5 =0 using completing square method please 🙏
Can you do one with a wrench? Like 1/2x squared + x - 4?
7. 6. 3 inches
I love you man
Facts Bro, Facts
Multiply all terms by 3 to make the a value into a perfect square, then use c=(b/2)^2•(1/a) to complete the square.
c=(24/2)^2•(1/9)
c=12^2•(1/9)
c=144•(1/9)
c=16
3x^2-8x+5=0
9x^2-24x+15=0
9x^2-24x=-15
9x^2-24x+16=16-15
(3x-4)^2=1
|3x-4|=1
3x-4=1
3x=5
x=5/3 🏳️🌈
3x-4=-1
3x=3
x=1 🏳️🌈
Answer is (x-3)(3x+4). Simple. Multiply 3x12=36. Get factors of 36 i e 9x4 which give difference 5.. 1/3(3x-9)(3x+4)= (x-3)(3x+4) ans.
How can someone know the method to use in solving quadratic equations?
Pov:you have a test tomorrow
For first problem you do not need 1 hour to follow useless way . Just instead 12x put 4x+8x and make 2 groups and start to
factor . x*2+4x+8x+32=0 (x*2+4x)+(8x+32)=0 again factor x(x+4)+8(x+4)=0 again factor (x+4)(x+8)=0 if x+4=0 x=--4 and if x+8 = 0 x=--8 finish
yo don't trust this video it wrong. the problem at 5:17 is wrong. A negative divided by a positive is still a negative. which makes the whole problem wrong.
What are you smoking 😂
13..minus. Haha
I still don't get it
ts does not make sense bro
Teach me your ways dude. You're a pro at this.💀🤌🏾
