Question

factorise x to the power 9 - y to the power 9 plz... answer me fast as possible

Answer 1

x^9-y^9

(x^3)^3-(y^3)^3

(x^3-y^3){(x^3)^2+(x^3)(y^3)+(y^3)^2}

(x-y)(x^2+xy+y^2){x^6+y^6+(x-y)^3}

Hope it helps you...✌✌

Thankyou AS@@

Answer 2

x^9 - y^9 = (x^3)^3 - (y^3)^3

= (x^3 - y^3){(x^3)^2 + (y^3)^2 + x^3y^3}

= (x^3 - y^3)(x^6 + y^6 + x^3y^3).
