Polynomials are a fundamental concept in mathematics, extensively used in algebra and calculus. They represent mathematical expressions composed of variables and coefficients, often involving addition, subtraction, multiplication, and exponentiation. One crucial aspect when dealing with polynomials is determining their degree – a measure of the highest power of the variable in the expression. Understanding how to calculate the degree of a polynomial is essential for various mathematical operations, such as simplifying expressions, factoring, and solving equations. In this article, we will explore the steps and techniques required to accurately calculate the degree of a polynomial, providing readers with a solid foundation in this fundamental aspect of algebra.

Polynomial means “many terms”, and can be used to refer to a range of expressions that include constants, variables, and exponents. For example, “x-2” is a polynomial; So does “25”. To determine the degree of a polynomial, all you need to do is find the largest exponent in that polynomial.

Steps
Polynomial containing At most One Variable
- With the expression 5x 2 – 3x 4 – 5 + x, you remove the constant and the coefficient gets x 2 – x 4 + x.
-x 4 + x 2 + x.
A Polynomial Containing Many Variables
- x 5 y 3 z + 2xy 3 + 4x 2 yz 2
- x 5 y 3 z = 5 + 3 + 1 = 9
- 2xy 3 = 1 + 3 = 4
- 4x 2 yz 2 = 2 + 1 + 2 = 5

Advice
- The instructions above outline the steps you need to take. You don’t have to do all the steps on paper, but it’s better to put them on paper the first time you do these steps because it’s hard to make mistakes when you do them on paper.
- By convention, polynomials with no degree are negative infinity.
- In step 3, terms like x can be written as x 1 and non-zero constants like 7 can be written as 7 x 0
