Question

Determine o quociente e o resto das divisões
A) (2x³-9x²+3x-6)÷(x-2)
B) (6a³-7a²+2a+1)÷(3a²-5a+3)

Answer 1

Resposta:

a) usando a regra de Ruffini

x³ x² x¹ x°

2. 2 -9 3 -6

4 -10 -14

````````````````````````````````````````````````````

2 -5 -7 -20

verificamos que:

Quociente

Q(x)=2x²-5x-7

o resto

R(x)=-20

b)6a³-7a²+2a+1 | 3a²-5a+3

-6a³+10a²-6a | 2a+1

````````````````````````````````````` |

0+3a²-4a+1 |

-3a²+5a-3 |

`````````````````````````````` |

a-2 |

Q(x)=2a+1

R(x)=a-2

espero ter ajudado, saudações a partir de Moçambique...
