Should only be x=1
(%i1) solve([log(x)*x=0], [x]);
(%o1) [x=1,x=0]
Should only be [x=1,x=0]
Should only be x=1
The alternative solver (to_poly_solve) can not solve this equation either:
(%i13) load(to_poly_solver)$
(%i12) %solve([log(x)*x=0], [x]);
Division by 0
(%o12) %union()
Thanks for this report--I'll try to fix to_poly_solve function.
I think you mean "should only be [x=1]".
Maxima actually got lucky here, because x=0 is arguably a solution by continuity, since limit(log(x)*x,x,0) = 0 (even for negative x).
I'm only interested in real results.
Is it possible to configure maxima, ony to get real results in this case?

As mentioned in a posting below, the solution x=0 might be considered as a solution too.
