Types of algebraic expressions may further be distinguished in the following five categories.

They are: monomial, polynomial, binomial, trinomial, multinomial.

**1. **Monomial: An algebraic expression which consists of one non-zero term only is called a monomial.

Examples of Monomials:

**a** is a monomial in
one variable a.

**2. **Polynomial: An
algebraic expression which consists of one, two or more terms is called a
polynomial.

Examples of polynomials:

**2a + 5b** is a polynomial
of two terms in two variables a and b.

**3xy + 5x + 1** is a
polynomial of three terms in two variables x and y.

**3. **Binomial: An
algebraic expression which consists of two non-zero terms is called a binomial.

Examples of binomials:

**m + n** is a binomial
in two variables m and n.

**4.** Trinomial: An
algebraic expression of three non-zero terms only is called a trinomial.

Examples of trinomial:

**x + y + z** is a trinomial
in three variables x, y and z.

**5.** Multinomial: An
algebraic expression of two terms or more than three terms is called a
multinomial.

**Note: **binomial and trinomial are the trinomials.

Examples of Multinomial:

**p + q **is a multinomial of two
terms in two variables p and q.

**a + b + c **is a multinomial of
three terms in three variables a, b and c.

**a + b + c + d **is a multinomial of
four terms in four variables a, b, c and d.

These are the types of algebraic expressions explained with various types of examples.
