Abstract

If be a polynomial of degree n such that aj=aj+ibj where aj and bj, j = 0, 1, ….., n are real numbers. In this paper we obtain a generalization of well known result of Eneström -Kakeya concerning the bounds for the moduli of the zeros of polynomials with complex coefficients which improve upon some results due to A. Aziz and Q.G Mohammad and others.
