I have a litle problem in solving a rather simple equation with mathematica: Here are the lines in mathematica x1 = 5; x2 = 7; U = (Sqrt[(1-pi0) x1] -1)^2; ro = (1+pi0 x2+U+Sqrt[(1+pi0 x2+U)^2-4 x2 pi0])/2; eq = x2 (1-ro)^2/ro +x2 U/ro - (ro - pi0 x2/ro)Sqrt[U x1/(1-pi0)]==0; NSolve[eq, pi0] There mathematica cannot solve this equation and find the values of pi0 that solves the problem while mapleV find them to in 2 seconds, as I am a beginner in mathematica I would be happy to get some help on this problem, moreover is it possible to determine the domain in which the solution has to be found while using the Solve or NSolve commnad??
