摘　　要：In this paper, a new proof of the inequality of Vicente Goncalves was given. The method may be powerful to deal with some problems of polynomials. As an application, a new inequality for the coefficients of a polynomial and its roots was derived.In this paper, a new proof of the inequality of Vicente Goncalves was given.
