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
