Answer 2

Step-by-step explanation:

Answer :

$\boxed{\sf x = \frac{1 + \sqrt{10} }{2}}$

or

$\boxed{\sf x = \frac{1 - \sqrt{10}}{2}}$

Explanation :

[refer the attachments]

formulae used :

$\boxed{\sf tan^{-1}(x) - tan^{-1}(y) = tan^{-1} (\frac{x - y }{1 + xy})}$

factor formula,

$\boxed{\sf x =\frac{-b\pm\sqrt {b^{2}-4ac}}{2a}}$
