To factor the expression (a^3 - 2a^2 - 4a = -8), follow these steps:
- Rewrite the equation as (a^3 - 2a^2 - 4a + 8 = 0).
- Factor out the greatest common factor, which is 1: (a(a^2 - 2a - 4) + 8 = 0).
- Factor the quadratic expression (a^2 - 2a - 4) using the quadratic formula or factoring techniques. The factors are ((a - 2)(a + 2)).
- Rewrite the expression with the factored quadratic: (a(a - 2)(a + 2) + 8 = 0).
- The factors of the equation are (a(a - 2)(a + 2) + 8 = 0).

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.
