Combining Like Terms with the Distributive Property

Mrs. Feld explains the distributive property and combining like terms in algebra. She provides three examples, demonstrating how to apply the distributive property and then combine like terms to simplify expressions. The lesson emphasizes the importance of understanding the signs of terms when combining them and provides step-by-step guidance for each example.

What is the first step in using the distributive property?

• Multiply the number outside the parentheses by each term inside the parentheses

• Divide the number outside the parentheses by each term inside the parentheses

• Subtract the numbers inside the parentheses

• Add the numbers inside the parentheses
