2016-09-07 11:36:53 +0200	commented question	Need help to simplify a long equation. I used the simplify_full() function, but with no results. This is the equation: Well, i need a simplification which gives me a fraction, and specify which is the numerator and denominator. Also, i want to reduce the number of variables to be regrouped. I want something like in example below : expr = x/(x^2 + x) expr.simplify_full() 1/(x + 1) Thank you! :)
