Exercise 40 Page 114

Let's rewrite each term as a product of - 0.25 and some other factor. To do so, note that that product of two negative numbers gives a positive number. 1{ 7g &= {\color{#FD9000}{\text{-} 0.25}} \cdot (\text{-} 28z) \\[0.5em] 3.5 &= {\color{#FD9000}{\text{-} 0.25}} \cdot (\text{-} 14) } Now we can use the Distributive Property to factor the expression. Let's go!

7g+3.5

SplitIntoFactors

Split into factors

- 0.25 * (- 28g) +(- 0.25)* (- 14)

FactorOut

Factor out - 0.25

- 0.25[- 28g+(- 14)]

AddNeg

a+(- b)=a-b

- 0.25(- 28g-14)
