Classification of polynomials 

1. Zero degree polynomials are used to describe quantities that don’t change.

2. 1st degree polynomials are used to describe quantities that change at a steady rate. They are also used in many one-dimensional geometry problems involving length.

3. 2nd degree polynomials are used to describe quantities that change with some amount of acceleration or deceleration. They are also used in many two-dimensional geometry problems involving area.

4. 3rd degree polynomials are used in many three-dimensional geometry problems involving volume.
