Question
hi

i have a problem with horner method,and want you to just give me a short description about it,and tell me what does it do
i search it through internet i found this address: "http://en.wikipedia.org/wiki/Horner_scheme#Examples"
can you plZ describe for me the example (in the page that i gave you)?
(i don't know how it write the second rows "6 0 6" in the synthetic diagram )

thanx
Bita

Answer
It's already explained in the web page: Each entry in the second row is the product of the x-value (3 in this example) with the third-row entry immediately to the left

2 times 3 get 6
6 plus -6 to give 0
0 times 3 is still 0
2 plus 0 is 2.....

It works in a zigzag manner.
