#color(green)(=> (2 sec x + 1) * ( sec x - 1)#

#color(crimson)(1 + tan^2 x = sec ^2 x, " Identity"#

#sec ^2 x - sec x + tan ^2 x#

#=> sec^2 x - sec x + sec^2 x - 1#

#=> 2 sec^2 x - sec x - 1#

#=> 2 sec^2 x - 2 sec x + sec x - 1#

#=> 2 sec x (sec x - 1) + 1 * (sec x - 1)#

#color(green)(=> (2 sec x + 1) * ( sec x - 1)#

#(\sec x-1)(2\sec x+1)#

#\sec^2x-\secx+\tan^2x#

#=\sec x(\sec x-1)+sec^2x-1#

#=\sec x(\sec x-1)+(secx+1)(\sec x-1)#

#=(\sec x-1)(\sec x+\sec x+1)#

#=(\sec x-1)(2\sec x+1)#
