Question

$\frac{x + 2}{2} + \frac{2}{x - 2} = \frac{ - 1}{2}$
​

Answer 1

$\frac{x+2}{2} + \frac{2}{x-2} = -\frac{1}{2} \\\frac{2}{x-2} = -(\frac{x+2}{2}) - \frac{1}{2} \\\frac{2}{x-2} = [-(x+2)-1]/2\\\frac{2}{x-2} = \frac{(-x-3)}{2} \\(x-2)(-x-3) = 2(2)\\x^2-3x +2x +6 = 4\\x^2 +x -2 = 0\\S = -b/a = -1/1 = -1\\P = c/a = -2/1 = 2\\X' = -2\\x'' = 1$

Espero ter ajudado ;)
