Question

(2x-y)³-(x+y)³+(2y-x)³ please answer fast..... ​

Answer 1

(2x-y)^3=(2x)^3–3(2x)^2.y+3.2x.y^2 - y^3.

= 8x^3 -12x^2y + 6xy^2 - y^3 ,

(x+y)³=x³+y³+3x²y+3xy²,

(2x-y)^3=(2x)^3–3(2x)^2.y+3.2x.y^2 - y^3

8x^3 - 12x^2y + 6xy^2 - y^3.

16x^3-24x^2+12xy^2-2y^3-x^3-y^3-3x^2y-3xy^2

this is the answer.
