Find the real solution of the equation:

We have,  ……(i)
 ……(i)
Let  =
 = 
 
 
 [Since,
 [Since,  
  ]
 ]
 
 
On putting the value of  in Eq. (i), we get
 in Eq. (i), we get
 ……(ii)
 ……(ii)
We know that,
 , xy
, xy
So, (ii) becomes,
 =
 = 
 =
 = 
 
  
 

 or
 or 
 or
 or 
 or
 or 
 
  or x = -1
 or x = -1
 or
 or 
For real solution, we have x = 0, -1.
