[Maxima] question in solve "x^2+2*x-3>=0"

[Barton Willis]

Try this:

 (%i4) load("solve_rat_ineq.mac")$
 (%i5) solve_rat_ineq(x^2+2*x-3>=0);
 (%o5) [[x<=-3],[x>=1]]

The file solve_rat_ineq was added to Maxima this past summer, I think.
If load gives an error, you might need to install the newest version of
Maxima or get a copy of solve_rat_ineq.mac.
