Question

factorise x to the power 12 minus y to the power 12

Answer 1

x^12– y^12

It can be written as

(x^6)^2 - (y^6)^2

Take x^6 = X and y^6 = Y

So the equation becomes

X^2 - Y^2 which is a formula = (X-Y) (X+Y)

=> ( x^6 - y^6) (x^6 + y^6)

Check

Solving (x^6 - y^6) (x^6+ y^6)

= x^12 + x^6*y^6 - y^6*x^6 - y^12

= x^12 - y^12 which is the question. Hence, our answer is verified.
