DISEQUAZIONI LINEARI NUMERICHE IRRAZIONALI

$\frac{x + \sqrt{2}}{x - \sqrt{2}} - \frac{x - \sqrt{2}}{x + \sqrt{2}} > \frac{4}{x^{2} - 2}$ (R)
$\frac{2}{\sqrt{2} x - 1} + \frac{\sqrt{2} + 1}{2 x^{2} - 1} \geq \frac{\sqrt{2} + 1}{\sqrt{2} x + 1}$ (R)
$\frac{x + 2}{1 - \sqrt{3}} > \frac{x}{1 + \sqrt{3}}$ (R)
$\frac{x}{2} - \frac{2 x + \sqrt{5}}{3} \leq \frac{\sqrt{5} - 1}{\sqrt{5} + 1}$ (R)
