Answer 1

Answer:

-8√5 is ur required answer...

Step-by-step explanation:

come to solution...

$\frac{ \sqrt{5} - 2}{ \sqrt{5} + 2 } - \frac{ \sqrt{5} + 2}{ \sqrt{5 - 2} } \\ = > \frac{( \sqrt{5} - 2 \times \sqrt{5 } - 2) - ( \sqrt{5} + 2 \times \sqrt{5} + 2) } {( \sqrt{5} + 2) ( \sqrt{5} - 2) } \\ = > \frac{ { (\sqrt{5} - 2) }^{2} - { (\sqrt{5} + 2) }^{2} }{5 - 4} \\ \\ \\ (here \: we \: using \: the \: following \: rules \\ 1.( {a - b)}^{2} \: \\ 2.( {a + b)}^{2} \\ 3.(a + b)(a - b) \\then \: the \: result \: comes \: ..... \\ = > \frac{5 + 4 - 4 \sqrt{5} - 5 - 4 - 4 \sqrt{5} }{1} \\ = > - 8 \sqrt{5}$

hope it will help you ✌️
