The poles are 0,0,-11,-10
The zeros are -1.
Root locus exists when there is odd number of poles and zeros when seeing from a particular point.
Hie pole at -11 reaches zero at infinity; the pole at -10
reaches zero at -1. The two poles at origin have no poles. So. they
should reach zeros at infinity. So. definitely there is a breakaway
point between the poles that is at the origin itself.
Since three branches will approach to infinity at the infinite
gain, having an angle of asymptotes.
