In order to answer this problem, we need to add together similar terms. It is better to rearrange the terms so as to eliminate confusion and minimize the error in the calculation. There are three terms in the given equations, these are

a^3b

a^2b^2

and constant

therefore the answer is

-5a^3b - a^2b^2 + 4
