Location of zeros of polynomials

In this paper, we obtain a result concerning the location of zeros of a polynomial p(z) = a(0) + a(1)z + . . .+ a(n)z(n), where a(i) are complex coefficients and z is a complex variable. We obtain a ring shaped region containing all the zeros of a polynomial involving binomial coefficients and t, s-Fibonacci numbers. This result generalizes some well-known inequalities.
