Question

What is the first step when rewriting y = –4x2 + 2x – 7 in the form y = a(x – h)2 + k?

A.2 must be factored from 2x – 7

B.–4 must be factored from –4x2 + 2x

C.x must be factored from –4x2 + 2x

D.–4 must be factored from –4x2 – 7

Answer 1

B

Explanation:

Right on Edge

Answer 2

complete the square

first, the coeieicne infront of x^2 term musbe 1
so if you have
y=ax^2+bx+c
isolate x terms and undistribute a
y=a(x^2+(b/a)x)+c

B is answer
