please help me quickly​

Answer 1

Explanation:

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

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

Taking LCM and equating above equation to 0, we get

$\frac{x}{x} - \frac{2}{x} + \frac{ {x}^{2} }{x} = 0$

$\frac{ {x}^{2} + x - 2}{x} = 0$

${x}^{2} + x - 2 = 0$

${x}^{2} + 2x - x - 2 = 0$

$x(x + 2) - 1(x + 2) = 0$

$(x + 2)(x - 1) = 0$

$x + 2 = 0 \: \: \: \: \: \: \: x - 1 = 0$

$x = - 2 \: \: \: \: \: \: \: \: \: \: x = 1$
