[CRASH] plotfunc() fails
I'm trying to get all answers from a Van Der Waals cubic equation.

Here's the definition of variables:

I defined 'x' too (x:=0)

When trying to plot the following equation on CAS, the hourglass stays there forever.

Which doesn't happen on it's equivalent form, the standard cubic form:

Anyway, I just managed to get all 3 answers from both forms of my equation.
There are 4 ways to solve the equation, by using the following sintaxis:
  • With solve
    solve(equation,var)
    solve({equation},{var}) For multiple equations.
  • With fsolve
    fsolve(equation,var)
    fsolve([equation],[var])--> For multiple equations, but this one only shows 1 result in my case.
