Hi all, just signed up, wondering if anyone could look at a problem on a practice midterm of mine and explain why the limit is 1 and not 0

Factor,
$\lim_{x\to 0} \frac{x^2-2x+1}{x-1}$
Factor,
$\lim_{x\to 0}\frac{(x-1)(x-1)}{x-1}$
Thus,
$\lim_{x\to 0}(x-1)=-1$

thanks, but doesn't the problem read x --> 1? in that case you'd do 1-1 meaning the limit would be 0?
