New issue 1387 by asmeurer: solve(x+sqrt(x)-2,x) returns wrong solution http://code.google.com/p/sympy/issues/detail?id=1387 I was adding some tests from Issue 694 (http://code.google.com/p/sympy/issues/detail? can=2&start=0&num=100&q=&colspec=ID%20Type%20Status%20Priority%20Milestone%20Owner% 20Summary&sort=&id=694), when I got to test M21: solve(x+sqrt(x)-2,x) The solution is x=1, but SymPy returns [1,4]. The source of this is easy to see, as the solution of solve(x-sqrt(x)-2,x) is x=4, so SymPy is failing to recognize that sqrt(x) is the principle square root only. -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
