Location of zeros of polynomials

In this paper, we obtain a result concerning the location of zeros of a polynomial p(z)=a0+a1z+a2z2+⋯+anznp(z)=a0+a1z+a2z2+⋯+anzn, where aiai’s are complex coefficients and zz is a complex variable. This result sharpens Cauchy’s result, along with some of the other known results which were based on the classical Cauchy’s work. Moreover, a MATLAB code is developed to construct polynomials, and compare the bounds obtained by our result with these known results.
