[QUOTE="Nukedsodapop, post: 3966781, member: 556426"] I haven't done this in a long time, here's the problem Simplify the expression (the one's in()'s are fractions, and they're being divided by other fractions) (x/y^2) - (y/x^2) ---------------------- (1/y^2) - (1/x^2) //Edit, so I think I got it but I need to check my answer is it (x-y)(x^2+xy+y^2) ------------------------- (x+y)(x-y) That simplifies to (x^2+xy+y^2) ------------------------- (x+y) ???
