| Topic | Partial Fractions |
| Type | Repeated factor with x² in denominator |
| Difficulty | Moderate -0.5 This is a straightforward partial fractions question with a repeated linear factor and a simple linear factor. The setup is standard (A/x + B/x² + C/(2x-1)), requiring only routine algebraic manipulation to find coefficients. While worth 5 marks, it involves no conceptual difficulty beyond applying the standard algorithm, making it slightly easier than average. |
| Spec | 1.02y Partial fractions: decompose rational functions |
