Answer 1

$\frac{35 - 20 \sqrt{3} + 14 \sqrt{3 } - 24 }{49 - 16(3)} = \frac{11 - 6 \sqrt{3} }{1 } = 11 - 6 \sqrt{3}$

$\frac{35 - 20 \sqrt{3} + 14 \sqrt{3 } - 24 }{49 - 16(3)} = \frac{11 - 6 \sqrt{3} }{1 } = 11 - 6 \sqrt{3}$This is your required answer, hope this helps you, this is solved not copy pasted : )
