-1x^3y^3 + 3x^2y + 2xy

Step-by-step explanation:

first you find any like terms. 2x^3y^3 and 32x^3y^3 can be added together because they both have x^3y^3. When I was learning this, something that helped me find like terms (I had a lot of trouble) was say there is 2x^2 and 2x^3, they can't be added together because x^2 and x^3 are different- like turtles and tigers in zoos. They both have z but they shouldn't belong together.

Anyways, 2x^3y^3 + negative 3x^3y^3 would subtract 3x^3y^3 from 2x^3y^3 because 2x^3y^3 came before -3x^3y^3 in the sentence. That leaves you with-

-1x^3y^3

There is also x^2y and 2x^2y which adds up to 3x^2y. Think of these xy things as labels, just add the numbers at the front, only add ones with the same labels.

3xy and -xy add up to 2xy.

This leaved you with -1x^3y^3 + 3x^2y + 2xy

(-1x-cubed y-cubed + 3x-squared y + 2xy)

hope this helps.
