Easy -1.2 This is a straightforward quadratic inequality requiring only identification of critical points (x=2, x=-3) and testing regions or sketching a parabola. It's a standard textbook exercise with minimal steps, easier than average A-level questions which typically involve more techniques or problem-solving.
Follow through on their two critical values of \(x\); \(\pm2, \pm3\) only; curly brackets only; with this notation only

## Question 1:
| Answer | Marks | Guidance |
|--------|-------|----------|
| Critical values of $x$ are $2, -3$ | **B1** | Possibly seen in solution using set notation |
| $\{x : x < -3\} \cup \{x : x > 2\}$ | **B1ft** | Follow through on their two critical values of $x$; $\pm2, \pm3$ only; curly brackets only; with this notation only |
