To simplify the expression 8/(x^2-4) - 3/(x-2), we need to find a common denominator and combine the fractions. The common denominator is (x-2)(x+2).
Multiplying the first fraction by (x+2)/(x+2) and the second fraction by (x+2)/(x+2), we get:
8(x+2)/[(x-2)(x+2)] - 3(x+2)/[(x-2)(x+2)]
Simplifying the numerators, we have:
(8x + 16 - 3x - 6)/[(x-2)(x+2)]
Combining like terms in the numerator, we get:
(5x + 10)/[(x-2)(x+2)]
Therefore, the simplified expression is 5x + 10 divided by (x-2)(x+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.
