just doing homework

I assume the x2y and the xy2 are powers because the constant is usually written in front...

ok so first your going to combine like terms.

(x^2y + 3x + 2) - (2 + xy^2 + 3x)

2 - 2 = 0

x^2y - xy^2 = cannot be combined.

3x - 3x = 0

so final answer is x^2y - xy^2.

hope this helps.
