Let $P(z)$ be a polynomial of degree $n$ having all its zeros in $|z|≤k$, $k≤1$, then
for every real or complex number $β$, with $|β|≤1$ and $R≥1$, it was shown by A. Zireh et
al.  that for $|z|=1$,
In this paper, we shall present a refinement of the above inequality. Besides, we shall also generalize some well-known results.
