The okawa-denshi tool will give you the pole locations which are approximately:

\( 35.13354\;\pm j35.211184 \)

on a circle of radius 50Hz. That is if you select a Q of 0.707, which you would want to do as it provides a response which is maximally flat in the passband. It also shows the double pole at the origin as well as the transfer function. You hardly need a piece of software to map a pair of poles and a double zero at the origin.

For this configuration, with a Q ≈ 0.707, the poles will be located at an angle of 45° to the negative real axis on a circle of radius 50, which is the center frequency.
