Answer

$3a^{3}+4a^{3}b+17a^{2}b-17ab^{2}$

Work Step by Step

$17a^{2}b-16ab^{2}+3a^{3}+4ba^{3}-b^{2}a$ Rewrite the expression by putting all the $a$'s right after the coefficient in every term: $17a^{2}b-16ab^{2}+3a^{3}+4a^{3}b-ab^{2}=...$ Simplify the expression by combining like terms: $...=3a^{3}+4a^{3}b+17a^{2}b-(16+1)ab^{2}=...$ $...=3a^{3}+4a^{3}b+17a^{2}b-17ab^{2}$
