Mark the Correct alternative in the following:
For the equation 
, the sum of the real roots is
given |x|2+|x|- 6 = 0
When x > 0
It can be written as x2 + x – 6 = 0
(x+3)(x-2) = 0
X = 2
When x < 0
It can be written as x2 - x – 6 = 0
(x-3)(x+2) = 0
X = - 2
Therefore x = ± 2
Hence sum of the roots = 0.
