7. The Distributive Property
Continue to next subchapter

Exercise 78 Page 51

Recall the Distributive Property. Remember, only like terms can be combined.

- 12cd-15

Practice makes perfect

Using the Distributive Property, multiply each term inside the parentheses by 3.

3(- 4cd-5)
Distr

Distribute 3

3(- 4cd)+3(- 5)

Now that we have rewritten the expression, we can simplify.

3(- 4cd)+3(- 5)
MultPosNeg

a(- b)=- a * b

- 3(4cd)-3(5)
Multiply

Multiply

- 12cd-15

Since - 12cd and 15 are not like terms, the expression cannot be simplified any further.
