1. January 4, 2012 Happy New Year! Welcome back! Warm-up: Reflection of Trimester 1 1.What grade did you expect to receive for Trimester 1? Did you meet your expectations for the class? How did or didn’t you meet those expectations? 2.What could you do to improve for Tri 2 and 3? How could Ms. PD help you meet your PreCalc goals?

2. Trimester 2 Only two Quiz retakes will be allowed. Conduct grades will be based on your behavior in class – talking during a lesson, sleeping, failing to take notes, doing other assignments, etc. Effort grades will be based on late or missing assignments, getting extra help during lunch or break if needed, asking questions if you do not understand something, etc. You are responsible for all assignments if you are absent from class. This includes field trips and school assemblies. I will only remind you of missing assignments when I hand out progress reports every 2-3 weeks. Bring your graphing calculator to class everyday!

3. Trimester 1 Final HW due Friday worth 3 HW assignments Copy the problems that you did incorrectly on your final. (All problems with 0 or partial credit) Redo the problems throughout the week and turn it in on Friday. If you need help, come in during break or lunch, but do not wait till Friday to get all your questions answered.

4. Lesson 5.3 More on Dividing Polynomials Divide: (x 2 – 10x – 24) ÷ (x + 2) = (x – 12)(x + 2) x + 2 = x – 12 Step 1: Factor the polynomial. Step 2: Cancel common factors.

5. Example 1 Dividing a Monomial into a Polynomial (5ab 2 – 4ab + 7a 2 b)(ab) -1 = 5ab 2 – 4ab + 7a 2 b ab = 5b – 4 + 7a Step 1: Rewrite the monomial with -1 exponent. Step 2: Since the denominator does not have a ( - ) or ( + ), split the fraction. Step 3: Simplify each fraction.

6. Example 2 Using Synthetic Division (5x 3 – 13x 2 + 10x – 8) ÷ (x – 2) Step 1: Write down the coefficients for each term in power descending order. 5 -13 10 -8 Step 2: Write the opposite constant of the divisor and bring down the first coefficient. 2 5 Step 3: Multiply the divisor and the number, then combine with the next. x 10 = -3 -6 4 8 0 So, (5x 3 – 13x 2 + 10x – 8) ÷ (x – 2) = 5x 2 – 3x + 4

7. Practice makes Perfect! Divide the following: 1.(3b 4 - 6b 3 – 2b 2 + b – 6)(b + 1) -1 2. 3. (x 5 – 3x 2 – 20) ÷ (x – 2) HW 5.3: Pg. 236 #19, 21, 23, 25, 27, 29, 31
