Greatest Common Factor and Distributive Property

Mr. Buffington from Simplify Academy explains the greatest common factor (GCF) and the distributive property, showing how to use them to simplify expressions. The video covers finding the GCF of numbers, applying the distributive property, and combining both concepts to simplify expressions. Practice problems and shortcuts are provided to reinforce learning.

What is the main focus of the lesson introduced by Mr. Buffington?

• Solving quadratic equations

• Understanding calculus concepts

• Using the greatest common factor and distributive property

• Learning about geometry

What is the greatest common factor of 6 and 15?

• 2

• 3

• 6

• 5

When finding the greatest common factor, what should you focus on?

• The numbers only

• The variables only

• None of the above

• Both numbers and variables

What does the distributive property involve?

• Subtracting terms inside the parentheses

• Multiplying a number outside the parentheses by each term inside

• Dividing terms inside the parentheses

• Adding numbers inside parentheses

In the expression 3(2s + 5), what is the result of applying the distributive property?

• 6s + 15

• 2s + 15

• 3s + 15

• 6s + 5

What is the purpose of separating multiplication expressions with an addition sign in the distributive property?

• To make the expression more complex

• To simplify the expression

• To combine like terms

• To ensure proper calculation

How can the expression 3(2s + 5) be written differently?

• With a plus sign

• With or without a multiplication dot

• With a subtraction sign

• With a division sign

What is the result of multiplying 4 by each term in the expression (6x + 7)?

• 24x + 28

• 30x + 35

• 10x + 11

• 20x + 21

What is the first step in finding an equivalent equation using the greatest common factor?

• List all the variables

• Add all the terms

• List all the factors of each term

• Subtract the terms

What is the greatest common factor of 4x and 6?

• 1

• 2

• 3

• 4
