x^(3)+y^(3)+2x^(2)-2y^(2)" at vuloters "

If x:y = 3 : 2, then the ratio 2x^(2) + 3y^(2) : 3x^(2) - 2y^(2) is equal to :

The following are the steps involved in factorizing 64 x^(6) -y^(6) . Arrange them in sequential order (A) {(2x)^(3) + y^(3)} {(2x)^(3) - y^(3)} (B) (8x^(3))^(2) - (y^(3))^(2) (C) (8x^(3) + y^(3)) (8x^(3) -y^(3)) (D) (2x + y) (4x^(2) -2xy + y^(2)) (2x - y) (4x^(2) + 2xy + y^(2))

((x +y)^(3) + (x-y)^(3))/(2) -y (3x^(2) + y^(2)) = ______
