Answer:
[tex]y=x^2+16x+64[/tex]
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):
[tex]x^2+8x+8x+64=0[/tex]
Simplifying gives you:
[tex]x^2+16x+64=y[/tex]
