The sum of all real values of x satisfring the equation is
Given,
Clearly, this is possible when
I.
or
II.
or
III. Even integer
Case l: When
Case ll: When
Case III: When
Now, when
= 4 + 8 - 60 = - 48, which is an even integer.
When
which is not an even integer.
Thus, in this case, we get x = 2.
Hence, the sum of all real values of
