Maple solution is 100% valid given the proper (obvious) assumptions. The
fact that there might exist other solutions is irrelevant. It doesn't
make Maple answer bogus.
When I ask a student to solve an equation, I will certainly give a lot
more marks if he writes down one solution, possibly forgetting a few
other cases, than if he just does nothing.
