Question

What is the completely factored form of p4 – 16? (p – 2)(p – 2)(p + 2)(p + 2) (p – 2)(p – 2)(p – 2)(p – 2) (p minus 2) (p + 2) (p squared + 2 p + 4) (p minus 2) (p + 2) (p squared + 4)

Answer 1

D

Answer 2

(p-2) (p+2) ( p^2+4)

Explanation:

p^4 – 16

p^2^2 - 4^2

This is the difference of squares

(a^2 - b^2) = (a-b)(a+b)

(p^2 -4) (p^2+4)

Rewriting

(p^2 -2^2) (p^2+4)

We have another difference of squares

(p-2) (p+2) ( p^2+4)
