Finding the value of C for a perfect square

👉 Learn how to find the value c that completes the square in a quadratic expression. A quadratic expression is an expression whose highest exponent in the variable(s) is 2. It is of the form ax^2 + bx + c where a, b, and c are constants. The value c that we create is what will turn our quadratic expression into a perfect square trinomial. A perfect square trinomial is an expression that can be expressed in the form (x + a)^2.

Given a quadratic expression, ax^2 + bx + c, the value of c that completes the square in the quadratic expression is given by c = (b/2)^2.

[yhello]

Thank you for actually teaching me.

My teacher literally didnt teach me this and she expects me to do a packet on it, but hey I found my jesus

Right here ✊

This man teaches a whole section of quadratics in 1:43. Why can't the teachers?:/

[tealorlee]

god bless you and your math knowledge and skill of teaching! My teacher is a lil' calculator and works at light speed! Soarin' Flyin!

When this 1 minute video taught you better than a 30 minute class. You know there's something wrong.

[brianmclogan]

There not but yes simple is better right?

What about finding the B term when given the C term? Ex. X squared + Bx + 625

[meganjensen]

Thank you exactly what i needed and it was quick!

[emilyfc]

never thought I would love a man as much as I love you rn

[ginyu]

Thanks a lot, this was definitely a lot easier than I thought.

[venii]

i swear his yt profile picture looks like mr clean

So, I may or may not have found a way to complete the square if a isn't 1. Just input the b value into (b^2)/4a.

Awesome, thanks for the help! I don't understand why a lot of teachers have to make things so over-exaggerated when they can just teach it like this. I learned more in this 1 minute video than I did in my 2 hour math class.

Remember that (ax + c)^2 = (ax)^2 + 2axc + c^2

I never expected that lesson to be very fast and simple!

[LuffymanYT]

You teach better than my current teacher. Thanks for the very simple but effective explanation of finding c.

[eduardaferreira]

Just wanted to say Thank you. Now I finally understand it. I really appreciate all of your work and time, trying to teach millions of people. Really THANK

[add]

but what if the linear term or the b is not divisible by 2? do i need to use fraction? if so, how?

[Squeakys]

Finally a math teacher more worthy of 100x raise

[jonnyAF]

One of the best videos i have ever seen !!

[dimxlights]

Lol this is the exactly trinomial I have in my textbook that I'm looking for help with.
