Abstract
Let\(P(z) = \sum\limits_{j = 0}^n {a_j z^j } \) be a polynomial of degree n. In this paper we prove a more general result which interalia improves upon the bounds of a class of polynomials. We also prove a result which includes some extensions and generalizations of Eneström-Kakeya theorem.
