What are like terms?

Back

Like terms are terms in an expression that have the same variable and exponent. For example, 3x and 6x are like terms, while 3x and 4y are not.

How do you simplify the expression 3 + 5x + 8 - 2x?

Back

First, combine the constant terms (3 + 8 = 11) and then combine the like terms (5x - 2x = 3x), resulting in 11 + 3x.
