Answer
$14y^{3}-16a^{2}b^{2}-19$
Work Step by Step
$14y^{3}-9+3a^{2}b^{2}-10-19b^{2}a^{2}$
Rewrite this expression by putting the $a$ of the fifth term right after the coefficient:
$14y^{3}-9+3a^{2}b^{2}-10-19a^{2}b^{2}=...$
Simplify by combining like terms:
$...=14y^{3}+(3-19)a^{2}b^{2}-(9+10)=...$
$...=14y^{3}-16a^{2}b^{2}-19$
