RE: HP Prime - problem with Solve App
In CAS, the same approach, but with csolve, returns:

{[18/(3*4^(1/3)*((1/2)*√(3)*i+(1/2))),-6/(3*4^(1/3)*((1/2)*√(3)*i+(1/2))),3*4^(1/3)*((1/2)*√(3)*i+(1/2))],[-18/(3*4^(1/3)),6/(3*4^(1/3)),-3*4^(1/3)],[18/(3*4^(1/3)*((-1/2)*√(3)*i+(1/2))),-6/(3*4^(1/3)*((-1/2)*√(3)*i+(1/2))),3*4^(1/3)*((-1/2)*√(3)*i+(1/2))]}

Which is the exact real solution from fsolve along with the two exact complex solutions. I haven't checked, but I assume the two complex solutions are correct; making this approach much more powerful than the original solve app, which only returns real solutions.
