Question

Factorise x^8−y^8
And recheck it

Answer 1

Answer:

X^8-y^8=(x^4 +y^4)(x4-y4)

(X^4+y4)(x2+y2)(x2-y2)

(x4+y4)(x2+ y2)(x+y)(x-y)

Answer 2

AnswEr :

➟ x⁸ - y⁸

➟ (x⁴)² - (y⁴)² [(a² - b²) = (a + b)(a - b)]

➟ (x⁴ + y⁴)(x⁴ - y⁴)

➟ (x⁴ + y⁴)((x²)² - (y²)²)

➟ (x⁴ + y⁴)(x² + y²)(x² - y²)

➟ (x⁴ + y⁴)(x² + y²)((x)² - (y)²)

➟ (x⁴ + y⁴)(x² + y²)(x + y)(x - y)
