The zeros of a polynomial can be found by computing the eigenvalues of the corresponding companion matrix. However, in the case of multiple zeros, the calculated results are usually not as accurate as those for simple zeros. This problem is discussed and a new method is presented by ...

Lehmer's method for finding a zero of a polynomial is a procedure for searching the complex plane in such a way that a zero is isolated in a sequence of disks of decreasing radii. In this paper modifications of the method that improve its stability are given. The convergence of the method...
We find Zeros of a polynomial function by setting the function equal to 0. Examples 1-3 illustrate the concept of Zeros of polynomial functions using polynomial functions of degree two (quadratic functions). Example 1: Find the Zeros for . Since the degree of the polynomial is two, we must...
Synthetic division can be used to find the zeros of a polynomial function. According to the Fundamental Theorem of Algebra, every polynomial function has at least one complex zero. Every polynomial function with degree greater than 0 has at least one complex zero. Allowing for multiplicities, ...

4) Sketch a Graph of a polynomial with the given zeros and corresponding multiplicities. (note: the graph is not unique ) x = -5, of multiplicity 2 x = -1, of multiplicity 1 x = 2, of multiplicity 3 x = 4, of multiplicity 2 5) Find the zeros of the following polyno mial fun...
This process is shown to be globally convergent monotonically to the zeros of entire functions of genus 0 and 1 (and in certain cases of genus 2) ... MD Dawson - 《Numerische Mathematik》 被引量: 99发表: 1975年 A composite polynomial zerofinding matrix algorithm A globally convergent matrix...
Another reason is that this method already proves that the inequalities are or are not satisfiable Note that for checking satisfiability we know what signs each polynomial is required to have which can be used to prune cases making the whole operation much more efficient. It is probably possible...
