Question

What is the factored form of the expression?

s4 – 16

A. (s - 2)2(s + 2)2

B. (s - 2)(s + 2)

C. (s - i)(s + i)(s - 2)(s + 2)

D. (s - 2i)(s + 2i)(s - 2)(s + 2)

Answer 1

\[s^4 - 2^4\]
\[{(s^2)^2} - {(2^2)^2}\]
\[(s^2 - 4)(s^2+4)\]
\[(s-2)(s+2)(s^2+4)\]

Answer 2

so which one

Answer 3

s^2 + 2^2 = (s-2i)(s+2i)
