Thank you so much if you can help me solve this.. :)

If the problem says "solve" then they need to give you the other part of the equation. If they only gave you an expression, maybe they said "simplify". :?:
(X^2 - Y^2 ) / (X^2 - XY - 2XY^2)
The x^2-y^2 is a difference of squares so you can use the formula for that. The x^2-xy-2xy^2 has a common factor you can take out front to get x(x - y - 2y^2). I don't think there's anything more you can do with it.
