Answer 2

Answer:

$\frac{ 5 - 3 \sqrt{14} }{7 + 2 \sqrt{14} }$

$\frac{5 - 3 \sqrt{14} }{7 + 2 \sqrt{14} } \times \frac{7 - 2 \sqrt{14} }{7 - 2 \sqrt{14} }$

$\frac{35 - 10 \sqrt{14 } - 21 \sqrt{14} + 6 \times 14 }{7 ^{2} - {2 \sqrt{14} ^{2} } }$

$\frac{35 - 31 \sqrt{14} + 84}{49 - 56}$

119-31√14/-7
