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...

Allowing for multiplicities, a polynomial function will have the same number of factors as its degree. Each factor will be in the form (x−c)(x−c) where c is a complex number. The number of positive real zeros of a polynomial function is either the number of sign changes of the...
Learn what are the zeros of a function and find out how to find the zeros of a function. See examples, including linear, polynomial and quadratic...
When a function or polynomial is graphed on a x,y coordinate grid, it could possibly cross the x-axis. The point(s) at which the graph and the x-axis intersect are called zeros. Graphing calculators have functions that allow you to find the locations of these points if they exist. ...

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...
5) Find the zeros of the following polyno mial function and state the multiplicity of each zero. f (x) = x (x - 1)2 (2x + 1) (x + 4)3 6) Find a polynomial function of degree 3 with the given zeros. Write your answer in the form: f (x) = ax3 + bx2 + cx + d x...
Computing a zero of a smooth function is an old and extensively researched problem in numerical computation. While a large body of results and algorithms has been reported on this problem in the literature, to the extent we are aware, the published literature does not contain a globally converge...
