SIAM Journal on Numerical Analysis, Vol. 20, No. 5 (Oct., 1983), pp. 1023-1031 (9 pages) In this paper a scheme is presented to numerically evaluate the argument principle for a real polynomial on the ...

First, we need to find which number when substituted into the equation will give the answer zero. \(f(1) = {(1)^3} + 4{(1)^2} + (1) - 6 = 0\) Therefore \((x - 1)\)is a factor. Factorise the quadratic ...

The goal of this paper is to obtain some comparison inequalities for a linear operator between polynomials in the plane. The polynomials under study have constraints on their zeros and the estimates ...
