Question

X-1/x + 5/6 = 2x/(x+1) pfvr me ajudem...

Answer 1

.
Ola Raff 

x - 1/x + 5/6 = 2x((x + 1)

multiplique por 6x

6x² - 6 + 5x = 12x²/(x + 1)

(6x² - 6 + 5x )*( x + 1) = 12x² 

6x³ + 5x² - 6x + 6x² + 5x - 6 = 12x²

6x³ - x² - x - 6 = 0

raiz real
x1 = 1.1171

raízes complexas 
x2 = -0.47524 - 0.81810i
x3 = -0.47524 + 0.81810i
