Math Factor problem

[vegetation]

Hey guys,

The other day when I was tutoring at a community college, a student gave me a problem about factoring:

x^3+y^3-3x+3y

I couldn't figure out how to do this one, so if any of you can help me out, I greatly appreciate it!

p.s. possible helpful formula: x^3+y^3=(x+y)(x^2-xy+y^2)

(x+y)(x^2-xy+y^2) - (3x - 3y)
(x+y)(x^2-xy+y^2) - 3(x - y)

Um...that's all I got? Sorry...maybe it can't even go any farther. Someone with Maple/Mathematica might be able to help you.

mathematica just spits out the same equation as what you gave.
