y = 8(x2 + 4x) + 17

Form a perfect-square trinomial.

Answer 1

4, -32

Explanation:

Answer 2

y = 8(x + 2)^2 + -15

Explanation:

Factor out the leading coefficient.

y = 8(x2 + 4x) + 17

Form a perfect-square trinomial.

y = 8(x2 + 4x + 4) + 17 + -32

Write in vertex form.

y = 8(x + 2)^2 + -15
