Question

15. Calcule os quocientes:

a) (x² + 5x + 6) : (x + 2)

b) (2x2 + 6x + 4) : (x + 1)

c) (x³ - 6x² + 11x - 6) : (x - 3)
​

Answer 1

a) (x² + 5x + 6) / (x + 2)

((x+2)(x+3))/(x+2)

x+3

b) (2x² + 6x + 4) / (x + 1)

(2(x+1)(x+2))/(x+1)

2(x+2)

c) (x³ - 6x² + 11x - 6) / (x - 3)

((x-1)(x-2)(x-3))/(x-3)

(x-1)(x-2)
