| Type | Solve quadratic inequality |
| Difficulty | Easy -1.3 Part (a) is a straightforward linear inequality requiring only basic algebraic manipulation (collect terms, divide). Part (b) is a standard quadratic inequality requiring factorization and sign analysis, but follows a routine procedure taught early in C1. Both parts are textbook exercises with no problem-solving insight required, making this easier than average. |
