JEE Main 2026 Preparation: Question Papers, Solutions, Mock Tests & Strategy Unacademy » JEE Study Material » Mathematics » Monomial, binomial, trinomial and polynomials

Monomial, binomial, trinomial and polynomials

In the following article, we are going to know about Monomial, binomial, trinomial, and polynomials etc. in detail.

Table of Content
  •  

Algebraic expressions are formed by letters or alphabets that can be used to express numbers without providing their real values. The constants and Variables can be combined in an algebraic expression. A coefficient is any value that is put before and multiplied by a variable.

Algebraic expressions are divided into monomial, binomial, trinomial, and polynomial expressions.

Algebraic expressions

In mathematics, an algebraic expression is a formula that contains variables, constants, and algebraic operations (like addition and subtraction). The fundamentals of algebra teach us how to represent unknown values using letters like x, y, and z. These letters are coined as variables in this context.

In an algebraic expression, variables and constants are combined. 

Any value placed before and multiplied by a variable is referred to as a coefficient. 

Eg: 2×x=2x where 2 is the coefficient

Eg:  4y+3, where (4x+3) is the expression,4 is the coefficient, y is variable and 3 is constant

Refer to the following image to understand better

Terms frequently used as

  • A variable is something we don’t know the value of and it can take any value.
  • A coefficient is a well-defined constant value that is utilized with the variable term.
  • A word with a definite value is called a constant value.

How Can Algebraic Expressions Be Simplified?

We join like terms to simplify an algebraic statement. As a result, similar variables will be combined. The same powers will now be blended from similar variables. Let’s take an algebraic expression as an example and try to reduce it to its simplest form to better comprehend the concept. Let us say it this way:

4x-2ab+3x+y

=(4x+3x)-2ab+y

=7x-2ab+y

Monomial Expression

A monomial can be defined as the algebraic expression that contains only one term.

A monomial is an algebraic representation of a quantity. A monomial is essentially a polynomial with only one term.

Every number is thought of as a monomial.

3x is monomial where x is variable

3xy is monomial where x and y are variable

4a is monomial where a is variable

8y is monomial where y is variable

, and other monomial expressions are examples.

Binomial Expression

A binomial expression can be defined as the algebraic expression that contains two dissimilar terms.

A binomial is a mathematical expression that depicts two dissimilar algebraic words that represent a quantity and are related using the basic mathematics addition and subtraction operators. A binomial is essentially a polynomial with two terms. It’s possible that it takes two separate forms.

Binomials include

5xy + 8 is binomial where x and y are variable

XYZ + 3x is binomial where x,y, and z are variable

, and so on.

Trinomial Expression

A trinomial expression can be defined as the algebraic expression that contains three dissimilar terms.

A trinomial is a mathematical expression that depicts three dissimilar algebraic terms that represent a quantity and are related using the basic mathematics addition and subtraction operators. A trinomial is the polynomial which has three terms in it.

Trinomials include 

5xy + 8 is trinomial where x and y are variable

 xyz + 3x is trinomial where x,y, and z are variable

, and so on.

Polynomials Expression

A polynomial can be defined as the expression that has more than one term with non-negative integral exponents of a variable.

A polynomial is a mathematical expression that depicts three dissimilar algebraic words that represent a quantity and are related using the basic mathematics addition and subtraction operators. A polynomial is a mathematical expression that has more than three terms.

Polynomials are binomial and trinomial.

Polynomial expressions include are

4x+ by + ca is polynomial where x, y, b and a are variable

, x3 + 2x + 3 is polynomial where x is variable

, and so on.

Other Expression 

Aside from monomial, binomial, and polynomial there are different types of expressions, algebraic expressions can also be divided into two categories:

  1. Expressions in Numbers
  2. Expression with Variables

Expressions in Numbers

A numeric expression is made up of numbers and operations, but no variables are included. In mathematics, a numerical expression is a combination of integers ,numbers, , and mathematical operations including addition, subtraction, multiplication, and division. 10 + 5, 15 2, and so on are some examples of numeric expressions.

Expression with Variables

A variable expression is a formula that includes integers, variables,  and operations to explain an expression. Each expression consists of a set of terms. A term can be a variable, a signed number, or a constant multiplied by one or more variables. 4x + y, 5ab + 33, and so on are examples of variable expressions.

Conclusion:

In this article, we learned about algebraic expressions, frequently used terms in algebraic expressions such as coefficient, variable and constant. We also learned about types of algebraic expressions that are monomial, binomial, trinomial, and polynomial. Also other types of expressions with numbers and with variables.
