Simplifying (x3x2y)(xy2+y3)+(x2y+xy2)(x^3 - x^2y) - (xy^2 + y^3) + (x^2y + xy^2)

To simplify the polynomial expression (x3x2y)(xy2+y3)+(x2y+xy2)(x^3 - x^2y) - (xy^2 + y^3) + (x^2y + xy^2), first distribute the subtraction across the second polynomial by changing the sign of each term inside it: x3x2yxy2y3+x2y+xy2x^3 - x^2y - xy^2 - y^3 + x^2y + xy^2. Next, rearrange the terms to group like terms together: x3x2y+x2yxy2+xy2y3x^3 - x^2y + x^2y - xy^2 + xy^2 - y^3. Finally, combine the like terms by adding their coefficients. The terms x2y-x^2y and +x2y+x^2y add to zero, as do xy2-xy^2 and +xy2+xy^2, leaving the simplified result: x3y3x^3 - y^3.
