Combining Like Terms

Front

What are like terms?

Back

Like terms are terms that have the same variable raised to the same power. For example, 3x and 5x are like terms, while 3x and 4y are not.

How do you combine like terms?

Back

To combine like terms, add or subtract the coefficients of the terms that have the same variable. For example, 7y + 2y = (7 + 2)y = 9y.

Front

Simplify: 7y + 2y

Back

9y

What is the first step in simplifying an expression?

Back

The first step is to identify and group like terms together.

Front

Simplify: 3x² - x + 7 + 5x + 2 - 2x²

Back

x² + 4x + 9

Front

What is a coefficient?

Back

A coefficient is a numerical factor in a term. For example, in 4x, 4 is the coefficient.
