TopicInequalities
TypeRational inequality algebraically
DifficultyStandard +0.8 This FP2 inequality requires careful algebraic manipulation with sign considerations when multiplying by (x+3), solving a quadratic inequality, and then extending to absolute values. While systematic, it demands more sophistication than standard A-level inequalities and involves multiple cases, placing it moderately above average difficulty.
