```Hi, Kris,
this may be what you need:

eq = x/(1 + y) + y/x - 1 == 0

-1 + y/x + x/(1 + y) == 0

Numerator@Together[eq[[1]]] == eq[[2]]

-x + x^2 + y - x y + y^2 == 0

or you have in mind some further transformation?

Have success, Alexei

Hi,

is there a way to get a "proper" polynomial representation of results
that Mathematica gives?

Here is a "cooked up" example (my actual results in Mathematica a
fairly complicated expressions):

Suppose the result is:

x/(1 + y) + y/x - 1 = 0

I'm looking for something that gives me:

x^2 - x + y^2 = 0

Thanks in advance
Kris
