| 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 requiring only direct substitution into the formula and basic arithmetic. It's easier than average because it involves a small positive integer power (n=6), asks for only the first three terms, and requires no problem-solving or manipulation beyond the standard expansion procedure. |
| Spec | 1.04a Binomial expansion: (a+b)^n for positive integer n |
Find the first 3 terms, in ascending powers of $x$, of the binomial expansion of
$$( 3 - x ) ^ { 6 }$$
and simplify each term.\\
