## Binomial Expansion: Finding the general term of coefficients

Express  in partial fractions and hence obtain f(x) as a series in ascending powers of x, giving the first 3 non-zero terms of this expansion. Find the coefficient of in the expansion.

## PJC/I/Q5 Binomial Expansion: Finding the General Term of Coefficient

Express  as partial fractions and hence obtain f(x) as a series in ascending powers of x as far as the term x³. State the range of values of x for which the expansion is valid. Find the coefficient of  in the expansion, where n>1.
