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

you could...
3xy ( (xy(3yx) 5)
but that is not making it simpler 
Your answer is correct.

Find the derivative of sin(2x + 3y)= 3xy + 5y2. I have this so far 1) cos(2x+3y) * d/dx (2x+3y)= 3xy' + 3y + 5y' 2) cos (2x+3y) * [2 + 3y']= 3xy' + 3y + 5y' 3) 3y' cos (2x+3y) + 2cos(2x+3y)= 3xy' + 3y + 5y' 4) 3xy' + 5y'  (3y(cos(3x+3y)= …
