Q1 of 96 Page 6

Define zero or root of a polynomial.

The zeros are the roots, or where the polynomial crosses the axis. A polynomial will have 2 roots that mean it has 2 zeros. To find the roots you can graph and look where it crosses the axis, or you can use the quadratic equation. This is also known as the solution.
