The degree of a polynomial is given by the term or monomial with the highest degree.

A constant Polynomial: has a degree of 0

A linear Polynomial: has a degree of 1

A Quadric polynomial: has a degree of 2

A Cubic Polynomial: has a degree of 3

A Quartic Polynomial: has a degree of 4

A Quintic Polynomial: has a degree of 5

Examples

| This is a Quadratic Polynomial because it has a degree of 2.

| This is a cubic polynomial because it has a degree of 3.

x+5           | This is a linear polynomial because it has a degree of 1.

Why

By knowing how to recognize a polynomial by the degree it will make classifying polynomials easier and will save time when you are asked to classify a polynomial in future math situations.
