Explore If we see an arrow at the bottom of the page what do we do? If we see an arrow at the bottom of the page what do we do? If we see a detour arrow when driving, what do we do? If we see a detour arrow when driving, what do we do? If we see an arrow in math class what do we do? If we see an arrow in math class what do we do? Answer: we follow the arrow! Answer: we follow the arrow!

Explain What did we do with arrows yesterday in math class? What did we do with arrows yesterday in math class? * Example: - (a + b) = - a = - a + (- b) + (- b) Answer: we used them to distribute through the negative. Answer: we used them to distribute through the negative.

Elaborate Example 1: 8(2 ¼) = 8 ( 2 + ¼) New Vocabulary: Distribute - to pass onto all the terms Section 2.5 – Objective: to use the distributive property to simplify expressions = 8 ( 2 ) + 8 ( ¼ ) = = 18

2.5 Distributive Property Example 2: 5 (x + 2) Example 2: 5 (x + 2) = 5 ( x ) + 5 ( 2 ) = 5x + 10 Example 3: (6y + 7) 4 Example 3: (6y + 7) 4 = 4 · 6y + 4 · · 7 = 24 y + 28

2.5 Distributive Property Orally: From Yesterday - Combining Like Terms. Orally: From Yesterday - Combining Like Terms. 9 x + 5 x 9 x + 5 x = 14 x = 14 x 8 y – 6 y 8 y – 6 y = 2 y = 2 y What about... What about... 3n + 7n – 4n 3n + 7n – 4n = 10n = 10n – 4n – 4n = 6n = 6n

2.5 Distributive Property Example 4: 8(n – 1) + 3n Example 4: 8(n – 1) + 3n = 8(n) + 8(-1) + 3n = 8n – 8 + 3n = 11n – 8
