Answer by vleith(2983) (Show Source): You can put this solution on YOUR website!
Given
You can see there are three terms separated by 2 plus signs.
Looking at those three terms, you can see that each of them includes some power of x and some power of y.
First thing you want to do is factor out and common terms in each of those two variables.
The first term has x^3, then second has x^2 and the last one has just x.
So you can factor out an x

Now do the same thing for y

Now you need to see if the polynomial on the right can be factored further.
It can.

There are some good URLs you cna use to check your factoring
