Question

Given f(x) = 0.7x^4− 0.7x^3+ 2.3x^2+ 2
Use synthetic division to find f(1).

Answer 1

Synthetic division is the same that divide by a polinomial x-a using the Briot-Ruffini device?

Answer 2

I think this is the result:
1|0,7. -0,7. 2,3. 0. 2
|0,7. 0. 2,3. 2,3. 4,3

0,7x^3 + 0x^2 + 2,3x + (4,3/(x-1))

Answer 3

Ops sorry,I forgot the independent term 0,7x^3 + 0x^2 + 2,3x + 2,3 + (4,3/(x-1))

Answer 4

0_0

Answer 5

Find f(−2). Find f(5). like how do you do it.

Answer 6

f(-10)

Answer 7

You could use this guide to do this: http://en.wikipedia.org/wiki/Synthetic_division

Answer 8

Succes?

Answer 9

. . no, why do you have 2,3 and 3,4 ?

Answer 10

The pattern is: multiply and, after, sum, right? 2,3*1 + 0 = 2,3 and 2,3*1+2 = 4,3

Answer 11
