\huge\longmapsto\mathfrak{Answer}

=》


\sec {}^(2) (x) - tan(x) - 3

=》


\tan {}^(2) (x) + 1 - \tan(x) - 3

=》


\tan {}^(2) (x) - \tan(x) - 2

=》


\tan {}^(2) (x) - 2\tan(x) + \tan(x) - 2

=》


\tan(x) ( \tan(x) - 2) + 1( \tan(x) - 2)

=》


( \tan(x) + 1)( \tan(x) - 2)

so,

case - 1

=》


\tan(x) = - 1

case - 2


\tan(x) = 2
