Derived graphs are the graphs obtained by some kind of operation on a given and usually smaller graph. By studying the relations between a graph and its derived graph, one can obtain information on one depending on the information on the other. In this paper, we calculate the first and second Zagreb indices of two of the derived graphs, namely double and strong double graphs of circumcoronene series of benzenoid (Hm) by using a novel polynomial called vertex degree polynomial.
