[(y – x) / (x^2 *y)] + [(x + y) / (xy2)]
x2 + xy2
(2x2 + y2) / (x2y + 1)
( y2 + x2) / (x2y2)
thank you soo much for the help~~

Get a common denominator of x^2*y^2
[(y – x) / (x^2 *y)] + [(x + y) / (xy2)] = [(y – x)*y/ (x^2 *y^2)] + [(x + y) *x/ (x^2y^2)] = [(y – x)*y + (x + y) *x]/ (x^2y^2)
then expand and simplify the numerator...

I suppose you want to do the indicated addition. The lowest common denominator is x^2 y^2.
You can then evaluate the numerator terms formed and add them. I think you get the last answer.

= y.(y - x) / x²y² + (x + y).x / x²y²
= (y² - yx + x² + xy) / x².y²
= (y² + x²) / (x².y²)
