One way is to use the experimental qepcad package, which uses cylindrical algebraic decompositions to solve problems like this. You can see the documentation by doing: sage: qepcad? You'll need to install the qepcad software package: $ sage -i qepcad-1.50 Of course, using qepcad to solve the above inequality is something like using a sledgehammer to pound a nail, but it should work.
