Front

What are like terms?

Back

Like terms are terms that have the same variable raised to the same power. For example, in the expression 4x² + 3x + 2x, the like terms are 3x and 2x.

Front

What does it mean to simplify an expression?

Back

To simplify an expression means to combine like terms and perform any operations to make the expression as concise as possible.

Front

What is the distributive property?

Back

The distributive property states that a(b + c) = ab + ac. It allows you to multiply a single term by each term inside a parentheses.

Front

What are constants in algebra?

Back

Constants are fixed values that do not change. In the expression 3x + 5, the number 5 is a constant.
