### Examples

- Consider the polynomial
*x*^{2}– 7*x*+ 12.

The numbers 4 and 3 are roots of the polynomial; since, when*x*= 4 or*x*= 3, the polynomial is equal to 0. - Consider the polynomial 6
*x*^{2}+ 11*x*– 10.

The numbers \(\frac{2}{3}\) and – \(\frac{5}{2}\) are roots of the polynomial, since when*x*= \(\frac{2}{3}\) or*x*=*–*\(\frac{5}{2}\), he polynomial is equal to 0.
