Understanding Factor Pairs and Distributive Property

The video tutorial explains how to find the correct factor pair for the linear expression 2x + 8. It begins by defining a factor pair and emphasizes the need for an X in the pair. The teacher tests different combinations, ultimately identifying 2 and x + 4 as the correct factor pair.

What is a factor pair in the context of linear expressions?

• Two numbers that subtract to form a given expression

• Two numbers that divide a given expression

• Two numbers or variables that multiply to form a given expression

• Two numbers that add up to a given expression

Which of the following is a necessary component of a factor pair for the expression 2x + 8?

• A variable

• A negative number

• A constant number

• A fraction

What happens when you multiply 2 by 2x?

• You get 4x

• You get 2x

• You get 8x

• You get 6x

Why is the pair 2 and 2x not suitable for the expression 2x + 8?

• It results in 2x

• It results in 6x

• It results in 4x

• It results in 8x

What is the result of distributing 2 over x + 4?

• 2x + 8

• 2x + 4

• 2x + 6

• 4x + 8

What is the correct factor pair for the expression 2x + 8?

• 2 and 2x

• 2 and x + 4

• x and 4

• 2x and 4
