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

=> (2x-y+2)(2x-y+2)(2x-y+2)

=> 4x^2 -2xy +4x -2xy +y^2 -2y +4x -2y +4(2x -y +2)

=> 4x^2 +y^2 -4xy +8x -4y +4(2x -y +2)

=> 8x^3 + 2xy^2 -8yx^2 +16x^2 -8xy +8x -4yx^2 -y^3 +4xy^2 -8xy -4y^2 +4y +8x^2 +2y^2 -8xy +16x -8y +8

=> 8x^3 -y^3 +6xy^2 -12yx^2 +24x^2 +24x -16xy -2y^2 -4y +8

=> (2x)^3 - (y)^3 +6xy(y -2x) +24x(x + 1) -2y(8x +y +2) +8

=> (2x -y)(4x^2 +2xy +y^2) +6xy(y -2x) +24x(x + 1) -2y(8x +y +2) +8

=> (2x -y)(4x^2 +2xy +y^2) +6x{ y(y -2x) +4(x + 1) } -2{ y( 8x +y +2) -4}

You can solve it further...
If u want, but that's also correct.
