Not a Problem
CSolve(((l^(3)) - (2 * l^(2)) + (3-10*q )*l + 6*q) = 0,l)
has a wrong answer - give an empty term - that means no answer.
wxMaxima found a realy bad term, but at least has an answer. I'm afraid Giac gives up also...
Any Idea to find a solution?
The same problem 
How's this?
Yep, thanks,
that makes a similar monster term. I am only interested in the discriminant.
