Simplifying Expressions - Combining Like Terms and Distribution

Front

What are like terms in an expression?

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, 3x + 5x = 8x.

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.

How do you apply the distributive property to simplify an expression?

Back

To apply the distributive property, multiply the term outside the parentheses by each term inside the parentheses. For example, -4(-4d - 5) becomes 16d + 20.
