Find a polynomial of degree 3 whose zeros are -4, -2, and 3. If you “plug in” -4, -2, or 3 for X in the above parenthesis you get ZERO. Copyright © 2012 Pearson Education, Inc. Publishing as Prentice Hall.

For the polynomial, list all zeros and their multiplicities. 2 is a zero of multiplicity 1 because the exponent on the factor x – 2 is 1. –1 is a zero of multiplicity 3 because the exponent on the factor x + 1 is 3. 3 is a zero of multiplicity 4 because the exponent on the factor x – 3 is 4.
