Given :

Polynomial

To find :

A polynomial of degree 3

Solution :

Step 1 of 2 :

Define polynomial

Polynomial is a mathematical expression consisting of variables, constants that can be combined using mathematical operations addition, subtraction, multiplication and whole number exponentiation of variables

Step 2 of 2 :

Find an polynomial of degree 3

Degree of a polynomial is defined as the highest power of its variable that appears with nonzero coefficient

Let x be variable involved

Since we have to find a polynomial of degree 3

So highest power of its variable that appears with nonzero coefficient must be 3

Hence a polynomial of degree 3 is x³ + 1
