Answer 2

Answer:

$\frac{5 - \sqrt{10} }{5 + \sqrt{10} } - \frac{5 + \sqrt{10} }{5} \\ first \: rationalise \: the \: denomintor \\ \frac{5 - \sqrt{10} }{5 + \sqrt{10} } \times \frac{5 - \sqrt{10} }{5 - \sqrt{10} } - \frac{5 + \sqrt{10} }{5} \\ \frac{( {5 - \sqrt{10}) }^{2} }{ {5}^{2} - { \sqrt({10}) }^{2} } - \frac{5 + \sqrt{10} }{5}$

$now \: use \: the \: identity \: {a}^{2} + {b}^{2} - 2ab$

solve by yourself

I am giving you direct answer

$\frac{25 + \sqrt{10} }{15} \\ \frac{5 + \sqrt{10} }{3}$
