| Topic | Binomial Theorem (positive integer n) |
| Type | Expansion up to x^2 term |
| Difficulty | Moderate -0.8 This is a straightforward application of the binomial theorem requiring only direct substitution into the formula to find three terms. It's easier than average because it involves no problem-solving, just mechanical expansion with small positive integer powers and coefficients. |
| 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 $( 2 + 3 x ) ^ { 6 }$.\\
