### Polynomial

A polynomial is a finite sum of the form

##### Explanation

A polynomial of degree *n* consists of any number of powers of a variable *x*, multiplied by the coefficient *a _{k}*, where the terms are added.

The fundamental theorem of algebra says that this polynomial has *n* roots, which also may be complex.

##### Examples

Well-known examples are *y = ax + b* and *y = ax ^{2} + bx + c*, where you will immediately see that the sequence is changed.
