Question

Write a quadratic equation having the given solutions -8

Answer 1

Answer:

$y=x^2+16x+64$

Step-by-step explanation:

A quadratic needs 2 solutions, but since you only have 1, I am to assume that x = -8 twice (or multiplicity of 2).  If x = -8, then in factor form, it's (x + 8).  Muliplying that by itself twice:

(x + 8)(x + 8):

$x^2+8x+8x+64=0$

Simplifying gives you:

$x^2+16x+64=y$
