| Difficulty | Standard +0.3 This is a standard modulus inequality requiring squaring both sides or considering critical points (x = 3/2 and x = -2) and testing intervals. It's slightly above average difficulty as it involves systematic case analysis or algebraic manipulation, but follows a well-established technique taught in C3 with no novel insight required. |
