How do you combine like terms?

Back

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

What is the difference between like terms and unlike terms?

Back

Like terms have the same variable and exponent, while unlike terms do not. For example, 2x and 3x are like terms, but 2x and 3y are unlike terms.
