| Topic | Polynomial Division & Manipulation |
| Type | Simple Algebraic Fraction Simplification |
| Difficulty | Easy -1.2 This is a straightforward algebraic fraction simplification requiring only factorization of numerator and denominator followed by cancellation. It involves basic factoring skills (taking out common factors) with no problem-solving or conceptual depth—simpler than a typical A-level question which would involve multiple techniques or steps. |
| Spec | 1.02k Simplify rational expressions: factorising, cancelling, algebraic division |
1 Simplify $\frac { 20 - 5 x } { 6 x ^ { 2 } - 24 x }$.
