1. Simplifying Expressions using Distributive Property

2. Objective - To use the distributive property to simplify numerical and variable expressions. Distributive Property or Order of Operations Distributive Property It works! Why use the distributive property?

3. RECAP…. 3(2) You simply multiply the number in front of the parenthesis with each part inside the parenthesis. 3(x+2) For example: 3(x+2) = 3x + = 3x+6

4. Simplify using the distributive property. 1) 2) 3) 4) 5) 6)

5. Simplify using the distributive property. 1) 2) 3) 4) 5) 6)

6. Distributive Property Practice 1.3( x + 4) = __________ 2.2( a + b) = __________ 3.6( t – 10) = __________ 4.8( 5 – t ) = __________

7. Distributive Property Practice 1.20( 3 – s) = __________ 2.10( 5 + w) = __________ 3.½( x + 6) = __________ 4. 15.5( s + 4) = __________ 5.7( b + 2.7) = __________

8. Cont. Examples 1. 5(2x+1) 2. 3(x +5) 3. 2 +3(x + 6)

9. Group Practice Try the following on your own 4.4 + 6(3 – x) 5.2(x + 4) +3 6. 2(x + 6 + 3)

10. Group Practice (con’t) 4. 4 + 6(3 - x) 5. 2(x+4)+3 6. 2(x+ 6 – 3)
