You can put this solution on YOUR website!
simplify:
1/x^2-1/y^2 fraction bar 1/x-1/y
-------
Numerator simplified: (y^2-x^2)/(x^2y^2)
----
Denominator simplified: (y-x)/xy
----------------------------------
Invert the denominator and multiply:
[(y^2-x^2)/(x^2y^2)] * [(xy)/(y-x)]
----
Cancel what you can to get:
-----
= (y+x)/(xy)
