Answer 1

Answer:

(2x - y + 2)^3

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

= 8x^3 - { y^3 + 2^3 + 3(y^2)(2) + 3(y)(2^2) } - 12x^2(y + 2) + 6x{y^2 + 2^2 + 2(y)(2)}

= 8x^3 - y^3 - 8 - 6y^2 - 12y - 12x^2y - 24x^2 + 6xy^2 + 24x + 4y

= 8x^3 - y^3 - 12x^2y + 6xy^2 - 24x^2 - 6y^2 + 24x - 8y - 8
