Answer:
Mathwords: Multiplicity. How many times a particular number is a zero for a given polynomial. For example, in the polynomial function f(x) = (x – 3)4(x – 5)(x – 8)2, the zero 3 has multiplicity 4, 5 has multiplicity 1, and 8 has multiplicity 2.

How do you find the multiplicity?
Image result for Multiplicity example
The factor is repeated, that is, (x−2)2=(x−2)(x−2), so the solution, x=2, appears twice. 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.
