TopicInequalities
TypeCombined linear and quadratic inequalities
DifficultyModerate -0.8 This is a straightforward C1 inequalities question requiring basic algebraic manipulation for part (a), factorising and solving a quadratic inequality for part (b), and finding the intersection of solution sets for part (c). All techniques are routine for this level with no problem-solving insight needed, making it easier than average but not trivial due to the quadratic factorisation step.
