The problem was that the command poly_reduced_grobner(eqs,vars); had never worked for me. (even after waiting for about 2 hours). A couple hours ago I installed Maxima 5.42.0 and wxMaxima 18.02.0. The command load(grobner) failed and the command solve([x^2+xy+y^2-12, x+y+x^2y^2-12],[x,y]); returned the desired answer with all solutions. Thank you! wxMaxima version: 18.02.0 Maxima version: 5.42.0 Maxima build date: 2018-10-06 14:34:08 Host type: x86_64-unknown-linux-gnu System type: gcc -g -fmessage-length=0...

solve does not find all solutions of a nonlinear system

integrate gives a negative result
