To solve the equation , we
need to consider two cases: one where is positive and one where it is
negative.
Case 1: is positive
If is positive, then the equation
becomes . Solving for gives:
Check the condition:
Is when
3(-12) + 12 = -36 + 12 = -24 < 0
So this solution is invalid for this case.
Case 2: is negative
If
