hope it is helpfull.

Answer 2

Answer:

$\frac{ \sqrt{5} - 2 }{ \sqrt{5} + 2 } - \frac{ \sqrt{5} + 2 }{ \sqrt{5} - 2}$

$\frac{ (\sqrt{5} - 2) \times (\sqrt{5} - 2) }{ ( \sqrt{5} + 2) \times ( \sqrt{5} - 2) } - \frac{( \sqrt{5} + 2) \times ( \sqrt{5} + 2)}{( \sqrt{5} - 2)( \sqrt{5} + 2) }$

$\frac{5 + 4 - 4 \sqrt{5} }{5 - 4} - \frac{5 + 4 + 4 \sqrt{5} }{5 - 4}$

$\frac{9 - 4 \sqrt{5} }{1} - \frac{9+ 4 \sqrt{5} }{1}$

$9 - 4 \sqrt{5} - 9 - 4 \sqrt{5}$

$- 8 \sqrt{5}$
