To factor the expression (b+2)^2 - (b-2)^2, you can use the difference of squares formula, which states that a^2 - b^2 = (a + b)(a - b). Applying this formula, you get:

(b+2)^2 - (b-2)^2 = [(b+2) + (b-2)][(b+2) - (b-2)]

= (b + 2 + b - 2)(b + 2 - b + 2)

= (2b)(4)

= 8b

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.
