Question

Divida P por D
A) p(x)= 3x³ - 5x²+ 1, d(x)= x -3
B) p(x)= 4x⁴ - x³ + 2x - 3, d(x)= x-2
C) P(x)= x⁴ +3x³ - x² - 1, d(x)= x+2
D) p (x)= -6x⁴ + 5x³ - 4x - 3, d(x)= x+1

Answer 1

A)

3x³  - 5x²  +1           |    x-3

                                    3x² +4x+12  =Q(x)

-3x³+9x²

4x²+1

-4x²+12x

12x+1

-12x+36

R(x)=35

B) p(x)= 4x⁴ - x³ + 2x - 3, d(x)= x-2

Usando Briot Ruffini

        |      4    |    -1     |      0     |   2     |     -3    |   

2      |      4   |    7      |      14    |  30   |     57

                Q(x)= 4x³+7x²+14x+30             .....R(x)=57

C) P(x)= x⁴ +3x³ - x² - 1, d(x)= x+2

      |        1      |     3    |    -1   |    0     |    -1

-2   |        1     |      1    |    -3   |    6     |   -13

             Q(x)=x³+x²-3x+6         ...........R(x)=-13

D) p (x)= -6x⁴ + 5x³ - 4x - 3, d(x)= x+1

        |        -6     |        5     |     0    |    -4      |     -3

-1    |        -6      |      11    |    -11  |     7      |     -10

             Q(x)=-6x³+11x²-11x+7             ...R(x)=-10
