Simplifying (a3a2b)(ab2+b3)+(a2b+ab2)(a^3 - a^2b) - (ab^2 + b^3) + (a^2b + ab^2)

To simplify the polynomial expression (a3a2b)(ab2+b3)+(a2b+ab2)(a^3 - a^2b) - (ab^2 + b^3) + (a^2b + ab^2), first distribute the negative sign to the second polynomial, which changes the sign of each of its terms: a3a2bab2b3+a2b+ab2a^3 - a^2b - ab^2 - b^3 + a^2b + ab^2. Next, rewrite the expression without the parentheses, rearranging the terms to group like terms together: a3a2b+a2bab2+ab2b3a^3 - a^2b + a^2b - ab^2 + ab^2 - b^3. Finally, combine the like terms. The a2b-a^2b and +a2b+a^2b cancel each other out, as do the ab2-ab^2 and +ab2+ab^2, leaving the simplified result: a3b3a^3 - b^3.
