Abstract

In this article, we specify some sufficient conditions which yield some significant bounds for themoduli of zeros of polynomials with real or complex coefficients. The paper proves the main result of [M. H. Gulzar, S. Bashir, Bounds for themoduli of zeros of polynomials, International Research Journal of Advanced Engineering and Science, 2:2 (2017), 51–53] as a special case.
