How do you factor:

9x^2y^3 - 3x^3y^2 - 15xy

i got: 3xy(3xy^2 - x^2y - 5)

But how do you factor it further to simplify it?

Thx

1. you could...

3xy ( (xy(3y-x) -5)

but that is not making it simpler

the directions are to determine whether or not the equation is exact if so then solve it. the question is (x-y^3+ysinx)dx = (3xy^2+2ycosx)dy i solve and i got that it is exact because My is -3y^2+2ysinx and Nx is -3y^2+2ysinx
