Sažetak

Let P(z) be a polynomial of degree n with real or complex coefficients. In this paper we obtain a ring shaped region containing all the zeros of P(z). Our result include, as special cases, several known extensions of Enestrom-Kakeya theorem on the zeros of a polynomial. We shall also obtain zero free regions for certain class of analytic functions.
