Bug in a solve function
Try to solve the inequality: (x^31)*(x^24*x+4)/(x^25*x+6)>=0
The Prime's CAS returns the wrong answer {x>=1 AND x<=2, x>3}. The right answer must be a {x>=1 AND x<2, x>3}. Xcas returns the same result. Point x=2 must not be in the solution list. The same issue appears with the equation x/x=1. Prime's CAS and Xcas return the wrong answer {x}. Point x=0 must not be in the solution list.
