## Homework Statement

Find the Maclaurin series for f(x)= 1/ (1+x+X

^{2})

## Homework Equations

## The Attempt at a Solution

I think the book says I can just divide 1 by the Maclaurin series of (1+x+X

^{2}). And when i do this the original function is the answer (which makes sense).

But when I do it my finding the derivatives of f(x) and then using the formula I get f(x) = 1-x+x

^{3}.

So I was wondering if

1) Which way is correct

2) is the second one accurate.

Thanks
