To simplify the expression (2x - 3)^2 + (x - 5)(x + 5) - (x + 4), expand and combine like terms:
(2x - 3)^2 = (2x - 3)(2x - 3) = 4x^2 - 12x + 9
(x - 5)(x + 5) = x^2 + 5x - 5x - 25 = x^2 - 25
Now, combine the terms:
4x^2 - 12x + 9 + x^2 - 25 - x - 4
Combine like terms:
5x^2 - 13x - 20

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.
