1. SFM Productions Presents: Another saga in your continuing Pre-Calculus experience! 2.3Polynomial and Synthetic Division

2. Homework for section 2.3 p156#13-45 eoo, 55-73 odd

3. And because 2 is a zero, (x-2) is a factor… Presto: Long Division

4. (product of linear factors)

5. Try:

6. The Division Algorithm dividend diviso r quotien t remainder

8. Try: Product of linear factors… Product of linear and quadratic factors

9. Synthetic Division:only works if dividing by something that has the form of x- k You have to be dividing by a linear term. In Synthetic Division, all you use is the coefficients.

10. Try: 10-10-24-3 1 1 -3 -3 9 -1 -3 3 1 1 -3 -3 1

11. 10-10-24-3 1 9 3 1 -3 1 Original equation Depressed equation (dividend) (quotient) divisorremainder 

12. The Remainder Theorem An easy way to do find the f of something is to do the synthetic division in your head…

13. Go! Do!
