If you want the poles of the transfer function G(s) that's quite straightforward.

The poles are simply the roots of the equation

\(2s^2+3s+1=0\)

i.e. where the denominator of G(s) is equated to zero.

Oh, iam sorry I forget to give some information, this system is going to be regulated with feedback and its not supposed to be any residual error on step shaped setpoint change. In this task they specifically wants me to use this formula to find the poles but I just dont know how?
