Finish the assignment

Continue to next subchapter

Exercise 28 Page 381

Be careful with negatives when distributing.

- 8a - 8b

Practice makes perfect

We are asked to rewrite the given expression using the Distributive Property. To do so, we need to distribute - 8 to the terms inside the parentheses.

- 8(a+b)

Distr

Distribute - 8

- 8(a) + (- 8)(b)

MultNegPos

(- a)b = - ab

- 8(a) + [- 8(b)]

Multiply

- 8a + [- 8b]

AddNeg

a+(- b)=a-b

- 8a - 8b
