Question

$frac{ {x}^{2} - 2}{x + sqrt{2} }$
решите пожалуйста

Answer 1

$frac{x {}^{2} - 2}{x + sqrt{2} } \ \ frac{(x {}^{2} - 2) times (x - sqrt{2} ) }{(x + sqrt{2} ) times (x - sqrt{2} )} \ \ x {}^{2} - sqrt{2} {}^{2} \ x {}^{2} - 2 \ \ frac{(x {}^{2} - 2) times (x - sqrt{2)} }{ x{}^{2} - 2} \ \ x - sqrt{2}$
