Question

factorise x^6 - y^6 by using a suitable identity.​

Answer 1

Answer:

(x+y) (x^2-xy+y^3) (x-y) (x^2+xy+y^3)

Step-by-step explanation:

x^6 - y^6

(x^3)^2 - (y^3)^2

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

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

Using identity a^3+b^3 = (a+b) (a^2-ab+b^2) and

a^3-b^3 = (a-b) (a^2+ab+b^2)

(x+y) (x^2-xy+y^3) (x-y) (x^2+xy+y^3)
