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[]] == eq[] -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 -- Alexei Boulbitch, Dr., habil.
