# CLASSIFY POLYNOMIALS BY DEGREE

## About "Classify polynomials by degree"

Classify polynomials by degree :

Here we are going to see how to classify polynomials by degree.

## Constant Polynomial

A polynomial of degree zero is called a constant polynomial.

General form : p(x) = c, where c is a real number.

## Linear Polynomial

A polynomial of degree one is called a linear polynomial.

General form : p(x) = ax+b, where a and b are real numbers and a  0.

A polynomial of degree two is called a quadratic polynomial.

General form: p(x) = ax2 + bx + c where a, b and c are real numbers and a   0.

## Cubic Polynomial

A polynomial of degree three is called a cubic polynomial.

General form : p(x) = ax3 + bx2 + cx + d  where a,b,c and d are real numbers and a   0.

Let us look into some example problems based on the concept.

Example 1 :

Classify the following polynomial based on degree

x3 - x2

Solution :

Degree of the given polynomial is 3.

Hence it is cubic polynomial.

Example 2 :

Classify the following polynomial based on degree

3x2 + 2x - 1

Solution :

Degree of the given polynomial is 2.

Example 3 :

Classify the following polynomial based on degree

y + 3

Solution :

Degree of the given polynomial is 1.

Hence it is linear polynomial.

Example 4 :

Classify the following polynomial based on degree

4x3

Solution :

Degree of the given polynomial is 3.

Hence it is cubic polynomial.

Example 5 :

Classify the following polynomial based on degree

(5/2)y2 + 1

Solution :

Degree of the given polynomial is 2.

Example 6 :

Classify the following polynomial based on degree

√3x + 1

Solution :

Degree of the given polynomial is 1.

Hence it is linear polynomial.

Example 7 :

Classify the following polynomial based on degree

7

Solution :

Degree of the given polynomial is 0.

Hence it is constant polynomial.

Example 8 :

Classify the following polynomial based on degree

y3 + 3y

Solution :

Degree of the given polynomial is 3.

Hence it is cubic polynomial.
