Factors and zeros worksheet
A zero and a factor are the same fact written two ways: if 3 is a zero then x - 3 is a factor. Both directions are on this sheet, because students who can go one way often cannot go the other.

How to do these
Write a polynomial with zeros
- Each zero gives a factor: (x - 2), (x + 3), (x - 5).
- Multiply them out.
The answer is .
Where students go wrong
Copying the sign of the zero into the factor. A zero of -3 gives the factor (x + 3), not (x - 3), because it is the value that makes the parenthesis zero. Getting that backwards flips the whole polynomial.
Also called roots of a polynomial, zeros of a function or the factor theorem.
