To simplify (a^2+3a)/(a^2-3a-18), we can factor the numerator and denominator. The numerator can be factored as a(a+3), and the denominator can be factored as (a-6)(a+3). Therefore, the expression simplifies to a/(a-6).
The excluded values for the variable a are the values that make the denominator equal to zero. In this case, a-6=0, so a=6 is an excluded value.

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.
