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.

[@chimpanzee341]

Bro howwwwwwwwww

[@error-code-80154]

It was always easy, just never explained thoroughly and/or over time

[@gja5468]

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!

[@chronicallylivin7090]

This guy always makes things much more simpler, thanks !

[@AustinBrown-ud4dc]

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 would imagine SATs have more difficult mathematical concepts than ninth/tenth grade material. How did you do?

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

Thanks for the video, very helpful

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

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.

[@jevanbanks3856]

Jordan Denny I believe its on a computer, since it seems to track his movement across the screen even when hes not writing, much like a cursor

[@sophia-nd7tm]

its on a computer but hes drawing with a tablet

[@burtreynolds6163]

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.

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.

What I want to know is how can I make an entire equation just by being given the Vertex of origin and the Focus?

[@thesnowman2509]

because its not a traditional equation, not really at least. Its a relation

just realized its been 2 years so u prob know this by now lol

[@BrothersorTerraria]

how i understood it, by having the vertex version of a quadratic formula, you dont need to find the derivative of the function to find the break point and you can immidiatelly find the extremum of the function
