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

Example:
F1:='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

Most of the numerical tools are allowed. If that is the fastest way... well, that sucks...

How do I use the ROOT() for imaginary roots? And also, I read that CAS functions are lowercase such as solve(). So, why POLYROOT() is also disabled when CAS is disabled?

Thanks for your reply and help.
