What are terms that have a number but no variable called?

Short Answer

Expert verified

The terms that have a number but no variable are called Constants.

Step by step solution

01

Step-1 – Apply the concept of terms and like terms

In an algebraic expression, terms are separated by plus or minus signs.

The term coefficient refers to the number in front of the variable in any term of the expression.

A constantterm is the number which have no variable associated with it.

Like terms are the terms which have identical variable parts with same exponent on it.

02

Step-2 – Example

In the expression, 3x+2+5x, observe that there are three terms 3x, 2, and 5x which are separated by plus signs.

So, the terms of the given expression are 3x, 2, and 5x.

The terms 3x and 5x have identical variable associated with numbers, so these are like terms. But 2 is the term with no variable with it.

So, the constant term in the given expression is 2.

03

Step-3 – Identify the term having number but no variable

In any expression the terms that have a number but no variable with numbers, are called the constant terms.

Constant terms are the terms which have numbers only, there is no variable part with the constant terms.
