Question

Can anyone please help I am struggling with math and Noone wants to help me and I want to learn so does anyone understand HOW u factor this

Answer 1

Explanation:

256 = 16×16=4×4×4×4 = 4^4

X^4-4^4 = (x^2)^2 - (4^2)^2

Using algebraic identity a^2-b^2 = (a+b)(a-b)

We get (x^2+4^2)(x^2-4^2)

(x^2+4^2)(x+2)(x-2)
