Answer 2

$= ( {2x})^{3} + ( {3y})^{3} + 3 ({2x})^{2} (3y) + 3(2x)( {3y})^{2} \\ - [ ( {2x})^{3} + ( { - 3y})^{3} + 3 ({2x})^{2} ( - 3y) + 3(2x)( { - 3y})^{2} ] \\ = {8x}^{3} + {27y}^{3} + 36 {x}^{2} y + 54x {y}^{2} - [ {8x}^{3} - 27 {y}^{3} -36 {x}^{2} y + 54xy^{2} ] \\ = {8x}^{3} + {27y}^{3} + 36 {x}^{2} y + 54x {y}^{2} - {8x}^{3} + 27 {y}^{3} + 36 {x}^{2} y - 54xy^{2} \\ = 54 {y}^{3} + 72 {x}^{2} y \\ = 18y(3y ^{2} + 4 {x}^{2} )$
