| Type | Solve quadratic inequality |
| Difficulty | Moderate -0.3 This is a straightforward quadratic inequality requiring rearrangement to standard form, factorization or quadratic formula, and identification of the solution region. It's slightly easier than average as it's a standard C1 technique with clean numbers, but requires more than just recall—students must rearrange, solve, and interpret the inequality correctly. |
