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.

Front

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, 2x + 3x = 5x.

Front

What does it mean to simplify an expression?

Back

Simplifying an expression means to combine like terms and reduce it to its simplest form.

Front

Can you combine terms with different variables?

Back

No, you cannot combine terms with different variables. For example, 2x and 3y cannot be combined.

Front

What is the coefficient in the term 7x?

Back

The coefficient in the term 7x is 7.

Front

What happens if there are no like terms in an expression?

Back

If there are no like terms, the expression cannot be simplified further.
