# Binomial expansion

## Binomial expansion

(a) Find the first 3 terms, in ascending powers of x, of the binomial expansion of

$(2-3x)^{6}$

giving each term in its simplest form.

(b) Hence, or otherwise, find the first 3 terms, in ascending powers of x, of the expansion of

$\left&space;(&space;1+\frac{x}{2}\right&space;)(2-3x)^6$
