Answer 1

Step-by-step explanation:

$\frac{12}{3 + \sqrt{5} + 2 \sqrt{2}} \\ \frac{12}{3 + \sqrt{5} + 2 \sqrt{2} } \times \frac{3 + \sqrt{5} - 2 \sqrt{2} }{3 + \sqrt{5} - 2 \sqrt{2} } \\ \frac{12(3 + \sqrt{5} - 2 \sqrt{2} ) }{14 - 8} \\ \frac{12(3 + \sqrt{5} - 2 \sqrt{2}) }{6} \\ 6 + 2 \sqrt{5} - 4 \sqrt{2}$
