Exercise 33 Page 381

Be careful with negatives when distributing.

0.5xy - 0.5xz

Practice makes perfect

We are asked to rewrite the given expression using the Distributive Property. To do so, we need to distribute 0.5x to the terms inside the parentheses.

0.5x(y-z)

DiffToSum

a-b = a+(- b)

0.5x[y+(- z)]

Distr

Distribute 0.5x

0.5x(y) + 0.5x(- z)

MultPosNeg

a(- b)=- a * b

0.5x(y) + [- 0.5x(z)]

Multiply

0.5xy + [- 0.5xz]
