The number of times a given factor appears in the factored form of the equation of a polynomial is called the multiplicity. The zero associated with this factor, [latex]x=2[/latex], has multiplicity 2 because the factor [latex]\left(x - 2\right)[/latex] occurs twice.
Demonstrates how to recognize the multiplicity of a zero from the graph of its polynomial. Explains how graphs just "kiss" the x-axis where zeroes have even multiplicities.
How To: Given a graph of a polynomial function of degree n, identify the zeros and their multiplicities. If the graph crosses the x-axis and appears almost linear at the intercept, it is a single zero. If the graph touches the x-axis and bounces off of the axis, it is a zero with even multiplicity.

The number of times a given factor appears in the factored form of the equation of a polynomial is called the multiplicity. The zero associated with this factor, x = 2, has multiplicity 2 because the factor (x − 2) occurs twice. The x -intercept −1 is the repeated solution of factor (x + 1)3 = 0.
Jul 18, 2019 · The polynomial p (x)= (x-1) (x-3)² is a 3rd degree polynomial, but it has only 2 distinct zeros. This is because the zero x=3, which is related to the factor (x-3)², repeats twice. This is ...
