How to find Real Axis crossing pointsthe gain K inat break-in and breakaway points of a Root Locus Plot byon MATLAB

I would like to know how to find Real axis crossing point valuesthe break-in and breakaway points of a transfer function using root locus on MATLAB.

TF

MATLAB Code:

f = tf([1poly([4 1]3]),[1 poly([-1 -2]))
rlocus(f)

But how to get the K value inwhere the real axis crossing pointbreak happens?
