Question

Find the product of (x − 8)2 and explain how it demonstrates the closure property of multiplication.

A. x2 − 64; is a polynomial

B. x2 − 16x + 64; is a polynomial

C. x2 − 64; may or may not be a polynomial

D. x2 − 16x + 64; may or may not be a polynomial

Answer 1

x2 − 16x + 64; is a polynomial

Answer 2

B

Explanation:

(x-8)^2=(x-8)(x-8)=x^2-8x-8x+64=x^2-16x+64
