# Confusion with Taylor series

1. The problem statement, all variables and given/known data

f(x)=$\frac{4x}{(4+x^{2})^{2}}$

2. Relevant equations

$\frac{1}{1-x}$ = $\sum$ x^{n}

3. The attempt at a solution

How am I supposed to use that equation to solve the main problem. I have the solution but I don't understand how to do any of it. My professor is horrible, been on academic probation for 7 years, and doesn't teach us anything. Just writes on the board

Sorry I meant to say MacLaurin series. A friend told me I have to solve it using infinite series but that still has me confused

Wait... what is the problem exactly?
