Question

Factorise the given equation -

​

Answer 1

x8 - y8

= (x4)2 - (y4)2

= (x4 - y4) (x4 + y4)

= (x2)2 - (y2)2 (x4 + y4)

= (x2 - y2) (x2 + y2) (x4 + y4)

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

Answer 2

(x⁴)²-(y⁴)²

(x⁴+y⁴)(x⁴-y⁴)

(x⁴+y⁴){(x²)²-(y²)²}

(x⁴+y⁴){(x²+y²)(x)²-(y)²}

(x⁴+y⁴){(x²+y²)(x+y)(x-y)
