| Topic | Partial Fractions |
| Type | Simplify algebraic fractions by addition or subtraction |
| Difficulty | Standard +0.3 This is a standard algebraic fractions question requiring factorisation of denominators, finding a common denominator, and simplification. While it involves multiple steps (factorising x²+2x and x²-4, combining fractions, simplifying), these are routine C3 techniques with no conceptual difficulty or novel insight required. The 7 marks reflect the working steps rather than exceptional difficulty, making it slightly above average but still straightforward. |

Express $\frac{3}{x^2 + 2x} + \frac{x - 4}{x^2 - 4}$ as a single fraction in its simplest form. [7]
