Simplify Expressions

Front

What are like terms?

Back

Like terms are terms that have the same variable raised to the same power. For example, in the expression 3x + 5x, both terms are like terms because they both contain the variable x.

Front

How do you combine like terms?

Back

To combine like terms, add or subtract the coefficients of the terms that are alike. For example, in the expression 3x + 5x, you combine them to get 8x.

Front

What is a coefficient in an algebraic expression?

Back

A coefficient is a numerical factor in a term of an algebraic expression. For example, in 4x, 4 is the coefficient.

Front

What does it mean to simplify an expression?

Back

To simplify an expression means to reduce it to its simplest form by combining like terms and performing any possible operations.

What is the first step in simplifying the expression -6x + 4(-x - 3)?

Back

The first step is to distribute the 4 to both terms inside the parentheses: 4 * -x and 4 * -3.
