As long as the range of values for x stays within the set of real numbers, then:
|x2| = x2
As the square of a real number will always be positive anyway.
If on the other hand, x belongs to the set of imaginary numbers, then:
|x2| = -x2
The reason for that is that in the case of imaginary numbers, x2 will give you a negative number. Its absolute value then would be the negative of that.
And with complex numbers it's, well... complex:
(ai + b)2 = -a2 + 2abi + b2
So:
|(ai + b)2| = a2 + 2abi + b2
