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, in 2x + 3x, you add the coefficients (2 + 3) to get 5x.

What is the coefficient in the term 7a?

Back

The coefficient is 7, which is the number multiplying the variable a.

Front

What is a constant term?

Back

A constant term is a term that does not contain any variables. For example, in the expression 3x + 5, the number 5 is a constant term.

Simplify: 5a + 2b - 3a + 4

Back

2a + 2b + 4

What is the first step in combining like terms?

Back

The first step is to identify all the like terms in the expression.
