Answer 2

Step-by-step explanation:

$\frac{6 - 4 \sqrt{2} }{6 + 4 \sqrt{2} }$

$= \frac{6 - 4 \sqrt{2} }{6 + 4 \sqrt{2} } \times \frac{6 - 4 \sqrt{2} }{6 - 4 \sqrt{2} }$

$= \frac{ {(6 - 4 \sqrt{2} )}^{2} }{36 - 32}$

$= \frac{36 - 48 \sqrt{2} + 32}{4}$

$= \frac{68 - 48\sqrt{2} }{4}$

$= 17 - 12 \sqrt{2}$
