Warm-Up #1 Name: For #1-2, model each expression. Then simplify the expression. Expression Model Simplified 1. 3(2x + 1) 2. 2(3x – 2) In #3-4, simplify the expression. Models are optional. 3. 4(x + 1) 4. –2(x + 3) Warm-Up #1 Name: For #1-2, model each expression. Then simplify the expression.

(3x + 2) ( x - 2) = 0

3x (x-2) + 2(x - 2)  *distributive property of multiplication

3x² - 6x + 2x - 4

3x² - 4x - 4 = 0

2/3 * 1/8 = 2*1 / 3*8 = 2/24 :

2/24 can be simplified into 1/12. 

divide 2 by 2 to get 1. divide 24 by 2 to get 12.

3 3/4 ÷ 1 1/2

convert mixed fractions to fractions.

3 3/4 = (3*4+3)/4 = 15/4

1 1/2 = (1*2+1)/2 = 3/2

15/4 ÷ 3/2 ⇒ 15/4 * 2/3 = 15*2 / 4*3 = 30/12

30/12 can be simplified to 10/4

30 divide by 3 to get 10. 12 divide by 3 to get 4.

10/4 can be simplified to 5/2

10 divide by 2 to get 5. 4 divide by 2 to get 2.

5/2 can be a mixed fraction of 2 1/2.

30/12 = 2 6/12 can be simplified to 2 1/2.
