It outputs ∣x∣|x|∣x∣, which is −x-x−x if xxx is negative.
∣x∣=x|x| = x∣x∣=x when xxx is non-negative.
x=4x = 4x=4 or x=−4x = -4x=−4.
Consider 2 cases for 2x−32x - 32x−3.
Case 1: 2x−3≥02x - 3 \geq 02x−3≥0.
x=4x = 4x=4 or x=−1x = -1x=−1 is a solution.
Case 2: 2x−3<02x - 3 < 02x−3<0.
x=4x = 4x=4 or x=−1x = -1x=−1 are the correct solutions.
Always consider different cases based on signs.
Check each solution in the original equation.
