We know that 
\sec^{2}x = 1 + \tan^{2}x
So,
       1 + \tan^{2}2x = 1 -\tan2x
       \tan^{2}2x + \tan2x = 0\\ \\ \tan2x(\tan2x+1) = 0
 either
      tan2x = 0             or                     tan2x = -1                                                  (     \tan x = \tan \left ( \pi - \frac{\pi}{4} \right ) = \tan\frac{3\pi}{4} )
            2x = n\pi                       2x=n\pi + \frac{3\pi}{4}
               x=\frac{n\pi}{2}                        x=\frac{n\pi}{2} + \frac{3\pi}{8}
