Question

rewrite in vertex form
y = x^2+14x+50

Answer 1

The vertex formula is y=a(x-h)^2

a=1 and to find the vertex you have to use the formula -b/2a

-14/2(1) = -7 and that is the x! Fill in -7 for all the x's in y= x^2+14x+50 and you get 1 so your vertex is (-7,1) now just fill in everything into vertex form! y=1(x+7)^2+1

Answer 2

Oops I meant the vertex formula is y=a(x-h)^2+k :)

Answer 3

you are a life saver!!!!

Answer 4

so for the work after finding out the answer for x is -7 i would write the equation as
-7^2+14(-7)+50? @Anecia23

Answer 5

and y=1 (x+7)^2+1 is the finished answer in vertex form? @Anecia23

Answer 6

Yup!! :D
