Resposta:
a) (2x³-9x²+3x-6):(x-2) = (2x² - 5x -7) resto= -20
b) (6a³-7a²+2a+1):(3a²-5a+3) = (2a + 1) resto = (a-2)
Explicação passo-a-passo:
a)(2x³-9x²+3x-6):(x-2)
2x³-9x²+3x-6 x-2
- 2x³-4x² 2x² - 5x - 7 2x² . (x - 2) = 2x³ - 4x²
0 -5x²+3x-6 -5x . (x - 2) = -5x² + 10x
- (-5)x²+10x -7 . (x - 2) = -7x + 14
0 -7x-6
- (-7)x +14
0 -20
(2x³-9x²+3x-6):(x-2) = (2x² - 5x -7) resto= -20
b)(6a³-7a²+2a+1):(3a²-5a+3)
6a³ -7a² +2a+1 3a²-5a+3
- 6a³ -10a² +6a 2a + 1 (2a) . (3a²-5a+3) = 6a³-10a²+6a
0 + 3a² - 4a +1 1 . (3a²-5a+3) = 3a² - 5a + 3
- 3a² - 5a +3
0 a - 2
(6a³-7a²+2a+1):(3a²-5a+3) = (2a + 1) resto = (a-2)
