| Type | Combined linear and quadratic inequalities |
| Difficulty | Moderate -0.8 This is a straightforward two-part inequality question testing basic algebraic manipulation (linear inequality) and factorising a quadratic. Both are routine C1 techniques with no problem-solving required—students simply apply standard methods. The linear inequality is trivial, and the quadratic factors easily to (x-8)(x+2), making this easier than average. |
