I think that the way solve checks solutions is misguided. In a simple example like this there is no need to check the solutions. There are cases where it is needed to avoid spurious solutions (e.g. after unrad) but for a simple polynomial system like this the checking is unnecessary. -- Oscar -- You received this message because you are subscribed to the Google Groups "sympy" group.
