Popis:	The famous Enestrom-Kakeya theorem establishes upper bound for the moduli of the zeros of a polynomial p(z) with positive monotonic coefficients. In this paper we consider the Polar derivative of p(z) with certain notable restrictions on its coefficients and prove some glamorous results which provide generalizations and refinements of some well known results.
