1.7.1 Binomial expansion

Find the first three terms, in ascending powers of $x$ , of the binomial expansion of

$14+x\displaystyle \frac{1}{\sqrt{4 + x}}$

giving each coefficient in its simplest form.

[3]

Hence find the first three terms, in ascending powers of $x$ , of the binomial expansion of

$14−x2\displaystyle \frac{1}{\sqrt{4 - x^2}}$
