tan x + tan 2x + tan 3x - tan x tan 2x tan 3x = 0 
tan x + tan 2x + tan 3x ( 1 - tan x tan 2x ) = 0 
tan x + tan 2x = - tan 3x ( 1 - tan x tan 2x ) 
( tan x + tan 2x )/ ( 1 - tan x tan 2x ) = - tan 3x 
tan 3x = - tan 3x 
2 tan 3x = 0 
tan 3x = 0 
3x = 2kpi where k = 0, 1,2,3,4,5,.............. 
 x = 2 k pi/3 where k = 0 , 1, 2 ,3 , 4 , 5 , 6..............

Answer:

Step-by-step explanation:

tan x + tan 2x + tan 3x - tan x tan 2x tan 3x = 0 

tan x + tan 2x + tan 3x ( 1 - tan x tan 2x ) = 0 

tan x + tan 2x = - tan 3x ( 1 - tan x tan 2x ) 

( tan x + tan 2x )/ ( 1 - tan x tan 2x ) = - tan 3x 

tan 3x = - tan 3x 

2 tan 3x = 0 

tan 3x = 0 

3x = 2kpi where k = 0, 1,2,3,4,5,.............. 

 x = 2 k pi/3 where k = 0 , 1, 2 ,3 , 4 , 5 , 6.............
