14. Dividing Polynomials Using Synthetic Division

16. Comparison of Long Division and Synthetic Division of X3 +4x2-5x+5 divided by x-3

17. Steps of Synthetic Division dividing 5x3+6x+8 by x+2
Put in a 0 for the missing term.

18. ANSWER: Steps of Synthetic Division dividing 5x3+6x+8 by x+2
Put in a 0 for the missing term.

19. Using synthetic division instead of long division.
Notice that the divisor has to be a binomial of degree 1 with no coefficients.
Thus:

20. Example
Divide using synthetic division.

21. Divide using synthetic division.
Answer
Divide using synthetic division.

22. Divide using synthetic division.
Example
Divide using synthetic division.

23. Divide using synthetic division.
Answer
Divide using synthetic division.

24. Complete the problems below.
Find the value f(2) for the given function.
Use Synthetic Division to divide:
f(x)=x3- 4x2+5x+3
What do you notice?

25. The Remainder Theorem

26. If you are given the function f(x)=x3- 4x2+5x+3 and you want to find f(2), then the remainder of this function when divided by x-2 will give you f(2)
f(2)=5

28. Example
Use synthetic division and the remainder theorem to find the indicated function value.

29. Example
Use synthetic division and the remainder theorem to find the indicated function value.
