Giovani · Answer 1

c. Multiple zero is 3; multiplicity is 2

Step-by-step explanation:

The factor is repeated, that is, the factor (x - 3) 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 = 3, has multiplicity 2 because the factor (x - 3) occurs twice.

Then

Multiple zero is 3; multiplicity is 2.
