| Topic | Binomial Theorem (positive integer n) |
| Type | Expansion up to x^2 term |
| Difficulty | Easy -1.2 This is a straightforward application of the binomial theorem with a small positive integer power (n=5). It requires only direct substitution into the formula and basic arithmetic with no problem-solving or conceptual insight needed. The question is more routine than average A-level questions, which typically involve multiple techniques or some element of problem-solving. |
| Spec | 1.04a Binomial expansion: (a+b)^n for positive integer n |
6 Find the first 3 terms, in ascending powers of $x$, of the binomial expansion of $( 2 - 3 x ) ^ { 5 }$, simplifying each term.
