Questionable Power Series for $1/x$ about $x=0$ WolframAlpha states that 
The power series for $1/x$ about $x=0$ is:
$$1/x = \sum_{n=0}^{\infty} (-1)^n(x-1)^n$$
This is supposedly incorrect, isnt it? 
This is showing the power series about $x=1$ in the form $(x - c)$
I dont understand how WolFramalpha says that is correct:

Thanks!

It is rather strange, because Wolfram Alpha is perfectly happy to return a Laurent series for e.g. 
series of 1/(x+x^2) at x = 0
Somehow, $1/x$ is treated differently.
