Question 768979: Please help.
Rationalize the denominator of √x+√y/√x-√y assuming x ≥ 0 and y≥0.

I'm not sure how to work this one, so I'm getting stuck.
√x+√y/√x-√y * √x+√y/√x+√y
x^2+xy+yx+y^2/x^2+xy-yx-y^2
yx+y^2/-yx-y^2 then I'm stuck as I'm obviously going down the wrong path.
Answer Options:
A. x+y/x-y
B. x+2√xy+y/x-y
C. √x-√y/√x+√y
D. x^2+y^2/x^2-y^2
