Abstract

Let P be a complex polynomial of the form P(z)=(λz-a)m Πn-mj=1(2-zj),where|zj|≥ 1,1 ≤ j ≤ n-m.The aim of this paper is to obtain generalisation of a result due to Zargar and Manzoor and a result due to Mir,Nazir and Wani.We shall also obtain an interesting bound which contains the zeros of the second derivative of P(z).
