Introduction to vertex form of a quadratic

Introduction to vertex form of a quadratic

[_tuling]

This really helped out during virtual school, this seemed like rocket science to me at first, now it’s like 1st grade math.

It’s 3 Am and I’m about to cry I have a math cumulative tomorrow and I have no idea what I’m doing

Missed a class and needed to catch up on some work. This was quick, efficient, and managed to teach a really good lesson whilst being under 7 minutes!

This guy always makes things much more simpler, thanks !

Who watchin this in quarantine rn for school?

[AustinBrown-uddc]

The greatest explanation for this. Had to come back to this video after a few months and this is the only video that refreshes my memory.

I didn’t know it was this easy. I feel kinda stupid now lol

[liakze]

thank you mr. salmon khan, without this I would not be able to complete my quarantine homework!

THANK YOU!!! I spent weeks trying to understand this but I couldn’t. After 3 minutes of watching this video I completely understand now!!! Thanksss 😄

I’m taking the SAT tomorrow. Hello cram session

[NamrataPrasad]

This is exactly what I needed to watch!

Does anyone know if all the writing is done on a computer with a mouse, or if it's on some sort of tablet. If it's a computer, he's god.

this is pretty cool, I like this video a lot. I learn stuff so yeah good very nice nice

[burtreynolds]

Thank you so much for this explanation! It really helps to understand WHY the x-component is the negative of "h." It's always better to understand than to just memorize.

i have a test tommorow :|, thank you. I now understand vertex form :)

So I'm a parent, my 14 yo just brought this to me. I last did math in the late 80s (86 - 89 high school) and went all the way to calc I before i stopped math. Was this taught back then? I remember the first two completely, remember FOIL, remember the and then the quadratic formula that was x= the -b +/- stuff. However when I looked at this vertex form it looked like nothing I've seen before.

When was it introduced in US math? Where was it hiding in the 80s? I'm really curious as I don't even remember my now 22 yo doing this (older sibling) or my 20 yo kids doing it.

I'm 26 having to re-learn high school math from scratch because my old teachers just told us to memorize formulas like they're magical incantations instead of explaining or visualizing why they even made sense, so I inevitably forgot all of it as soon as those classes were over. These videos are way more effective, i almost think teachers should just put these on for their class instead of trying to teach their own way

But what if you have to solve forrrr a
