## How To Find The Roles of Variables in a Rational Expression

When you are solving an equation, it is important to know the role of every variable.

In this section, we will take a look at how to find the role of a variable in an expression.

A variable can have one of three roles:

– A coefficient or constant term

– An independent or dependent variable

– A function

## What Can Be Done With An Expression?

Expressions are sets of mathematical symbols that are used to represent a problem or equation.

The two most common types of expressions are rational and algebraic. A rational expression is an expression that has a fractional component, such as 3/4, 5/6, or 4/5. An algebraic expression is an expression that is only made up of integers and operations on them, such as (2x+3)+(7x-8).

Expressions can be used in many different ways. For example, they can be used to solve various types of problems in math class or when solving for the unknown variable in an equation.
