How do you determine if the expression is a Polynomial?

For determining if the expression is a Polynomial or not, you should always remember the polynomial rules. Check the rules and decide whether the given expression is a polynomial or not.

Is x^3+2x^-2+ 4/x+5 a polynomial?

The given x^3+2x^-2+ 4/x+5 expression is not a polynomial as it contains negative exponents and denominator variables.

What are the different types of polynomials?

Polynomials are categorized into different types, such as Monomials, Binomials, Trinomials, and Quadrinomials. If you can't be sure about whether the expression is Trinomials or Quadrinomials, then you can just call it a polynomial. If the polynomial has a degree of two, then it is known as quadratic. If it has a degree of three, it can be called a cubic.

What is Polynomial? How to Determine It?

An expression that contains two or more algebraic terms is known as a polynomial. Often, they are the sum of several terms having various powers (exponents) of variables.

In Greek, the word Polynomial means 'multiple terms' as the Poly refers to multiple and Nomial means terms.

Polynomials often represent a function ie., f(x)=∑ rk ⋅ x^k;

If you want to know the process of determining if the expression is polynomial or not, read the polynomial rules mentioned below and check for polynomial.

If the expression breaks any of the rules of what isn't an expression then it is not said to be a polynomial. So, make use of these polynomial rules and easily determine if the expression is a polynomial or not.

Else, Go with our handy & free online tool to determine if the expression is a Polynomial in just a few seconds with detailed steps.

Polynomial Rules: What Makes Up Polynomial

Polynomial is a mix of terms isolated with the signs called + or - and also for quick understanding of how to find it easily, we have come up with the authentic rules to identify and know what polynomials include:

Polynomials contain variables, constants, exponents, and arithmetic operations (except division by variable).
The letters such as x, y, z, a, and b are called variables.
The constants are like whole numbers, for example, 3, 5, 11. These constants are placed with variables and also on their own in the polynomial expressions.
When it comes to Exponents there are generally linked to variables, and also with a constant. Examples of exponents in polynomials are 6² or x³.
Arithmetic operations play a vital role in forming a polynomial expression. For instance, multiplication is like 2x, multiplication & addition is like 6x+5, and subtraction is written as x-5.

If the given expression satisfies all the above rules then it is determined as a polynomial otherwise not. If you want to know what are those points that expression is not a polynomial look at the below modules.

Polynomial Rules: What ISN'T a Polynomial

Variables in fraction form.
Variables in the denominator don't make it as a polynomial expression, similar negative exponents as a^-b = 1/a^b
Other functions such as trigonometric, absolute values, logarithms, etc., and non-whole powers (roots) make not a polynomial expression.
Variable in exponents, for instance exp(x) = e^x

By following these rules and hints you can easily determine the expression is a polynomial or not. Learn more about the polynomials and their functions by going through our factorpolynomials.com designed polynomial calculators that help kids to find various concepts with ease.

Example:

Determine -8y^7-y^11+1+8y^13 is a Polynomial or not?

Solution:

The given expression -8y^7 - y^11 + 1 + 8y^13 can be written as 8y^13 - y^11 - 8y^7 + 1

To check for polynomial, firstly examine the given expression and check whether it matches with the rules or not.

If it does not match with the polynomial rules then the expression is not a polynomial.

Given 8y^13 - y^11 - 8y^7 + 1 expression is a polynomial as it is separate with + and - signs and followed all other rules as well.
