Answer 2

Explanation:

$\frac{ \sqrt{3} - 1}{ \sqrt{3} + 1 } + \frac{ \sqrt{3} + 1 }{ \sqrt{3} - 1 }$

$\frac{ ({ \sqrt{3} - 1)}^{2} + {( \sqrt{3} + 1)}^{2} }{ ({ \sqrt{3)} }^{2} - {1}^{2} }$

$\frac{ ({ \sqrt{3}) }^{2} - 2. \sqrt{3}.1 + {1}^{2} + {( \sqrt{3}) }^{2} + 2. \sqrt{3}.1 + {1}^{2} }{ { (\sqrt{3)} }^{2} - {1}^{2} }$

$\frac{3 - 2 \sqrt{3} + 1 + 3 + 2 \sqrt{3} + 1 }{3 - 1}$

$\frac{8}{2}$

$4$
