Why is the x - coordinate of the vertex -b/2a? Quadratic Equations?

THANK YOU THANK YOU THANK YOU. I HATE MEMORIZING. I LOVE ACTUALLY UNDERSTANDING IT. ❤❤❤

[@davidsiegel9943]

Great clear explanation, so good to understand why that works!

[@chengheekok3392]

What a good video!!!!!!!!!!!!!

[@gloriakalengelayi8294]

Thanks! Another good video. Do you have anymore of these types of videos why the maths works (proofs) I clicked on your websites but it seems to be down

[@gloriakalengelayi8294]

Is there a proof of why we do raise over run and not run over raise when calculating the slope?

[@gregoryb7595]

This was very clear! Thanks for the explanation!

[@alperkaya3334]

Very clear. Thank you!

thanks

This is perfect. Thank you!

Wow, so the vertex is hidden within the quadratic formula. The vertex plus or minus the discriminant/2a. And since the result is a zero, what does this mean? What is the discriminant/2a? Is that a distance between 0 and the vertex? In your example, you end up with vertex minus 5 (which equals x=-4)... and vertex plus 5 (which is x=6). That is wild. I never thought about it that way before. I'm curious what that right side of the QF means.

Pretty cool, right?! I was pretty blown away when I saw this myself!
