Hi, there-- THE PROBLEM: Factor each expression completely. 3x^2y^3+6x^2y-3xy A SOLUTION: Every term in your polynominal has at least one factor each of 3, x, and y. We factor out 3xy.The other polynomial xy^2 + 2x - 1 has no factors (other than 1 and itself.) We're done. Hope this helps! Feel free to email if you have any questions about the solution. Good luck with your math, Mrs. F math.in.the.vortex@gmail.com
