Complex Fraction problem?

Question

((x-((x²+y²)/y))/((1/x)-(1/y))) / ((x²+y²)/(x²-y²))
That looks like alot I know, but its easier once you write it out on paper the right way. I can get started, but my teacher said that the answer is only one term, and I keep getting more than that. Can anyone help?

to see it the normal written out way go to http://i3.photobucket.com/albums/y90/lazydaisy2828/problem.jpg

Answer 1

I tried but came up with:

((xy-x^2+y^2)*(x)*(x+y))
/
(x^2+y^2)
