vou tentar fazer as outras e mando pra vc

Answer 2

Resposta:

A) 8a²-10a+4 / 2a+1

-8a²-4a 4a - 7

----------

-14a + 4

+14a + 7

------------

11 ⇒ resto

tirando a prova:

(2a+1)(4a-7)

8a²-14a+4a-7+11

8a² - 10a + 4

B) 2a³-9a²+3a-6 / a-2

-2a³+4a² 2a²-5a - 7

------------

-5a²+3a

5a²-10a

------------

-7a - 6

7a - 14

-----------

-20 ⇒ resto

2a²-5a - 7 - 20 =

2a²-5a-27
