I've been searching through multiple videos and couldn't find one that used the vertex form till now. I think it would help if you memorize y=a(x-h)*square*+5 and put the opposite of h . Ex(-h,k)
If you're using the formula to find k. Will the numerator always be zero if c=0 or do you not add it to the (4ac-b^2)/4a when c=0? Cuz anything times zero is 0
huh. my teacher just told us to use 1, 3, 5. because if you look at the points they increase by two vertically and horizontally by 1 or whatever. and just multiply a with those numbers.
2:42 i was really confused how he got 3x=3y because i kept getting 3x=1y while solving, but looking at the 1x=3y it means 3x=1y which is the same as 3x=3y because both numbers are congruent. Just incase anyone else like me was confused lol
6 months later help arrives he puts in 2 which makes inside the ()=0 times 2 =0 leaving the 5 the max point is 2,5 based off that or the "highest" point of parabola
he got the positive two or one way he could've gotten positive 2 is doing the opposite of that number i got that from this way from the video th-cam.com/video/y99lNRqLjBA/w-d-xo.html
I tried the table but i ended up with getting the other values being greater tan my turning point. I have an equation f(X) = 2(x - #) + 1. PLEASE HELP !!!
khan if u explained it with h, k, and a i think it would make a lot more sense
k a holy crap you helped more than the video did! Ty!
Most do X y

Jk
Hands up if you have no idea T__T
start with knowing what a vertex form is...
You help me more than my real math teacher
oof

personally this made alot more sense to me that using h and k, thanks khan!
soo hard, man i always think math is easy and its also math my favorite subjec but everytime i do i fail:(
Thanks, needed this for SAT prep
How’s your life now?

How tf is your hand writing so good, also Great vid it helped a lot
teached a lot better than my teacher

By far the hardest section in algebra. No wonder its at the very end.
@@BoatsandCannons. this dude might not even be using youtube anymore (on this account)
Omg honestly TH-cam should be my math teacher! Thanks so much
I knows is an old video but it just saved my life thank you so much!!!
hey bro ur a real one bro 💯💯
🥰
you teach 10x better than my math teacher
how do you know what numbers to use for x?? like what you have done if 1 and 3 hadn't have matched??
My savior
God is our savior and yes, Khan is very good.
@@DanielAustin-p6p skibidi toilet rizz ohio
your so good at this thank u so much !!!!!!
Honestly this made no sense
Right
That was great Khan! :D
Who else watching this in the school washroom during the test
Valuable information, thanks
So much easier if you do h and k
This is very helpful, and very informative as well as familiar 😂
Your handwriting 😍😍
this was helpful ^_^
this confused me
imzie i am un grade 8 and i am doing this unless you are yonger than me be asameed
TECK CLARK A suggestion! start doing grade 10 math, when you can formulate a proper sentence.
lol

You're a lifesaver!
what about if the number in the parenthesis is a positive number. and the number an the right side is also positive.
Amir Shahid did you find out how to do it?
Thanks Khan.

thats what i do
Im crying over this homework
Looks like im gonna stay up until 5 am

What software are you using to graph and click and drag the points?
khan academy
what if the x is negative? will the 1 2 3 will be negative also?
Thanks you
I can never understand khan but I understand other TH-camrs
Thank you so much
GUYS WISH ME LUCK FOR MY EXAMINATION TOMORROW!
thank you very muchhh
Finally ; - ; .......
Lost me @ 1:25
6 months later help arrives
he puts in 2 which makes inside the ()=0 times 2 =0 leaving the 5
the max point is 2,5 based off that or the "highest" point of parabola
bryan wouldnt he get -2,5?
he got the positive two or one way he could've gotten positive 2 is doing the opposite of that number i got that from this way from the video
th-cam.com/video/y99lNRqLjBA/w-d-xo.html
Follow the vertex form formula and locate -h and k you’re gonna get y easily
*Dude graduated, Lol congrats.*
whats the program you're using called
Found it. The link was in the description. lol www.khanacademy.org/math/algebra/quadratics/vertex-form-alg1/e/graphing_parabolas_1?YT&Desc&AlgebraI
i was talking about the black board type thing
this would be so helpful if i knew the words for all those math-y terms in french.
thx
Doesn’t even help if the first number isn’t negative
i’ve had to watch this video like seven times but i think i get it now.....maybe.....we’ll see on my final tomorrow
@Rishabh Dagli i don’t remember but i’m doing well in ap calc now so i must’ve done alright!

did u figure it out.

@@superbluelordyt9544 omg i didnt even realize. mb lol
woo math
Thank you for making me more confused
Do you just switch the signs of whatever is inside the parenthesis?
Hi 🙋♀️
Yep.
Ms velasquez
1:02 what?
y didn't he include a positive "a" example as well
If you haven't learned linear regression before this you may be comfused.
why (2,5)??...in the equation is a -2
Sabrina The X coordinate in the vertex is always the opposite of H
this video make me funny haha
