| Topic | Inequalities |
| Type | Solve absolute value inequality |
| Difficulty | Standard +0.3 Part (a) requires squaring both sides to eliminate absolute values and solving a quadratic inequality - a standard technique. Part (b) involves rearranging a rational inequality and analyzing sign changes, which is routine for Further Maths students. Both are textbook-style exercises with clear methods, slightly above average difficulty due to the absolute value manipulation and rational inequality, but no novel insight required. |
