Find all real (a) such that (\fracax + 3x-2 \le 1) for all (x>2). → Hint: transform to (\frac(a-1)x + 5x-2 \le 0) and analyze numerator sign.
| Step | Description | |------|-------------| | 1 | Identify the of the expression (e.g., denominator ≠ 0, radicand ≥ 0) | | 2 | Eliminate absolute values using cases or squaring (if sign known) | | 3 | For rational inequalities, bring all terms to one side, combine into single fraction | | 4 | Create a sign chart (Villena uses number line with critical points) | | 5 | Write solution as union of intervals | | 6 | Verify edge points if inequality is non-strict (≤, ≥) |
