Question

Método de Briott Ruffini (3x³ +4) : (x -4)

Answer 1

x-4=0 ==>x=4

     |  3  |  0             |   0                 |   4
4   |  3  |  12+0=12 |   4*12+0=48  |  4*48+4=200

12x²+48x+200

Answer 2

$\text{P}(\text{x})=3x^3+4$

$\text{D}(\text{x})=x-4$

$+4~|~3~~~~0~~~~0~~~|~~4$
$.~~~~|~3~~~12~~~48~~|~196$

$\text{Q}(\text{x})=3x^2+12x+48$

$\text{R}(\text{x})=196$
