Question

x^8-256 use this identity =a^2-b^2 (a+b) (a-b)​

Answer 1

Step-by-step explanation:

x^8-256

x^8-2^8

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

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

Answer 2

Answer:

(x⁴+16)(x²-4)(x+2)(x-2)

Step-by-step explanation:

x⁸-256

={(x²)²}²-{(2²)²}²

={(x²)²+(2²)²}{(x²)²-(2²)²}

=(x⁴+16)(x²+2²)(x²-2²)

=(x⁴+16)(x²+4)(x+2)(x-2)
