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)

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

Step-by-step 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)
