Abstract

In this paper we consider the class of polynomials of the type $p(z)=z^s left(a_0+sum_{j=mu}^{n-s} a_j z^j ight)$, $1lemule n-s$, $0le sle n-1$ having some zeros at origin and rest of zeros on or outside the boundary of a prescribed disk, and obtain the generalization of well known
results

Keywords: Derivative, polynomial, inequality, Zeros
