Kennedy AdamsTo factor by grouping (x^2 - x - x + 1), first group the terms in pairs:
(x^2 - x) and (-x + 1).
Now, factor out the greatest common factor from each pair:
(x(x - 1)) and (-1(x - 1)).
Notice that both pairs have a common factor of ((x - 1)). Factor out this common factor:
((x - 1)(x - 1)).
Therefore, (x^2 - x - x + 1) factors as ((x - 1)(x - 1)) or ((x - 1)^2).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
