Concept wise  This video is only available for Teachoo black users

Polynomials are classified on degree.

If,  Degree = 3, it is cubic polynomial

Degree = 2, It is quadratic polynomial

Degree = 1, It is linear polynomial

Degree = 0, It is constant polynomial

 Degree Types of Polynomial 3 Cubic Polynomial 2 Quadratic Polynomial 1 Linear Polynomial 0 Constant Polynomial Find degree & type of polynomial

x 3 − 3x 2 + 4x + 10

-a-

Here, Degree = Highest Power = 3

So, it is  cubic polynomial.

-ea-

x 2 + 2x + 4

-a-

Degree = Highest Power = 2

-ea-

x + 30

-a-

Degree = Highest Power = 1

So, it is  linear polynomial.

-ea-

3

-a-

3 =  3 × 1

3 =  3 × 0

Degree = Highest Power = 0

So, it is  constant polynomial.
