Question

help

write in vertex form

f(x)=8x^2 + 8x - 12

Answer 1

I think that should be your answer

Answer 2

it's asking for an equation, not a graph

start by writing parentheses around the first two terms

f(x)= (8x^2 + 8x) - 12

Answer 3

then we factor out 8 from the expression inside the parentheses

f(x) = 8(x^2+x) - 12

Answer 4

then we take the coefficient in front of x (which is 1), divide it by 1, and then square it

Answer 5

(1/2)^2 = 1/4, and then we add this number to the inside of the parentheses

f(x) = 8(x^2+x+1/4) - 12

know where to go from here?

Answer 6

no

Answer 7

factor (x^2+x+1/4)
