Question

Write a quadratic equation having the given solutions -8

Answer 1

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

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`
