## Abstract We examine some properties of the 2βvariable greedoid polynomial __f__(__GΒ·,t,z__) when __G__ is the branching greedoid associated to a rooted graph or a rooted directed graph. For rooted digraphs, we show a factoring property of __f__(__GΒ·,t,z__) determines whether or not the rooted di
