not solved in CAS

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?

How's this?

SolveCubic(((x^(3)) - (2 * x^(2)) + (3-10*q )*x + 6*q) = 0)

Yep, thanks,


that makes a similar monster term. I am only interested in the discriminant.
