Zeros of polynomials & their graphs - Khan Academy
When studying polynomials, you often hear the terms zeros, roots, factors and x -intercepts. In this article, we will explore these characteristics of polynomials and the special relationship that they have with each other.
Zeros of polynomials: matching equation to graph
The concept of zeroes of polynomials is to solve the equation, whether by graphing, using the polynomial theorem, graphing, etc.
Zeros of polynomials (multiplicity) (video) | Khan Academy
Given the graph of a polynomial and looking at its x-intercepts, we can determine the factors the polynomial must have. Additionally, we can determine whether those factors are raised to an odd power or to an even power (this is called the multiplicity of the factors).
