In this short paper, we present a solution to Gutman's problem on the characteristic polynomial of a bipartite graph (Research Problem 134, Discrete Math. 88 (1991)). In [2] I. Gutman proposed a research problem which is stated as follows. The matchings polynomial of a graph G is defined by cl(G,x)
