RE: HP Prime without CAS
I don’t know what’s authorized but if the CAS is the only forbidden part of the calc, then the numerical tools are available.

My advice would be to use the Function app in combination with the ROOT numerical solver.

Example:
F2:='X^5+X^3-3*X^2-X+2'
Open the plot view to see where are the roots
Then solve numerically:
ROOT(F2,-1) -> −0.805154414085
ROOT(F2,0.5) -> 0.886557206985
ROOT(F2,2) -> 1

Regards.

Edit: corrected incoherence F1 vs F2 in my initial post
