-15x^3y - 3x^2y^3

Explanation:

A product is found by multiplying. Therefore to solve this problem we must multiply -3xy by each term in the parenthesis:

(-3xy)*(5x^2 + xy^2) ->

(-15x*x^2*y) - (3x*x*y*y^2) ->

(-15x^1*x^2*y) - (3x^1*x^1*y^1*y^2) ->

(-15x^(1+2)y) - (3x^(1+1)y^(1+2)) ->

-15x^3y - 3x^2y^3
