= r^4 - 16
= (r - 2)(r + 2)(r² + 4)
Answer: (r - 2)(r + 2)(r² + 4) are the factors.
= (r - 2)(r + 2)(r² + 4)
Answer: (r - 2)(r + 2)(r² + 4) are the factors.

(r² - 4)(r² + 4)
(r - 2)(r + 2)(r² + 4)
(r - 2)(r + 2)(r² + 4)

a^4 - b^4 = (a^2 + b^2)(a^2 - b^2) = (a^2 + b^2)(a + b)(a - b)
r^4 - 16
= (r^2 + 4)(r^2 - 4)
= (r^2 + 4)(r + 2)(r - 2)
r^4 - 16
= (r^2 + 4)(r^2 - 4)
= (r^2 + 4)(r + 2)(r - 2)

r ^4 - 16
=(r^2)^2- 4^2
=(r^2-4) (r^2+4)
=(r^2-2^2)(r^2+4)
=(r+2)(r-2)(r^2+4)
Please rate me if u find it useful.
