The degree of any given polynomial is the highest and most prominent power of the variable in a polynomial expression. To recollect, a polynomial is determined as an expression of more than two algebraic terms, particularly the sum of several terms that include different powers of the same or different variables. It is a linear blend of monomials.
What is the degree of a polynomial?
A polynomial’s degree is known to be the highest or the most leading power of a variable in any polynomial equation. The degree of a polynomial shows the highest exponential power in any polynomial. We know that the polynomial can be categorized into a polynomial with one variable as well as a polynomial with multiple variables. The polynomial with one variable is the greater power of the polynomial expression. But, if any polynomial with multiple variables, the degree of the polynomial can be found by combining the powers of different variables in any terms present in the given polynomial expression.
How to find the degree of a polynomial?
A Polynomial is the adding of variables assigned with the respective exponential powers and coefficients. The steps to find the degree of a polynomial are as given below:-
- Step 1: First combine all the similar terms that are in the terms with the variable terms.
- Step 2: Ignore all the existing coefficients
- Step 3: Then arrange the variable in descending sequence of their powers
- Step 4: Finally, the largest power of the variable is the degree of the given polynomial
Degree of a polynomial definition:
The degree of any respective polynomial is the most prominent power of a variable in the given polynomial equation. To learn the degree of a polynomial function, only the terms with variables are considered to find out the degree of that polynomial. The most leading exponential power of the variable term in the polynomial shows the degree of that polynomial.
What is the degree of a zero polynomial?
When all the existing coefficients are equivalent to zero, the polynomial is considered to be a zero polynomial as well. Hence, the degree of the zero polynomial is either undefined or established in a negative way.
What is the degree of a constant polynomial?
A constant polynomial has no set variables. Considering there is no exponent therefore no power to it. Thus, the degree of the constant polynomial is zero. For instance: For 5 or 5×0, degree = 0.
What is the degree of a polynomial with more than one variable?
The degree of a polynomial with more than one variable can be estimated by adding and unifying all the exponents of each variable in it together.

Tips and tricks
To find the degree of any given polynomial without any confusion, you can follow these approved and easy steps:
- Identify individual terms of the given polynomial.
- Combine all the identical terms, the variable terms and ignore all the constant terms.
- Arrange those terms in descending sequence of their powers.
- Then find the term with the most leading exponent and that defines the degree of the polynomial.
Below are stated some important and primary points related to the degree of a polynomial:
- The degree of a polynomial with only one variable is the largest exponent of the variable available in the polynomial.
- The degree of a polynomial with more than one variable is to find the degree of the polynomial, one will first have to recognize each term of that polynomial, as to find the degree of each term you add the exponents to it.
- The degree of a rational expression is to take the degree of the top that is the numerator and subtract the degree of the bottom also known as the denominator.
- The degree of any unspecified polynomial expression with a root such as 3√x is 1/2.
