Factorization is really important when we're trying to find limits in math. Sometimes, if we just try to plug in numbers, we end up with confusing results like $\frac{0}{0}$.

Here are some key ideas to remember:

1. Simplification: Factorization helps us break down expressions. We can cancel out common factors to make things easier.

2. Indeterminate Forms: When we use factored forms, we can solve the limits without hitting any undefined expressions.

3. Efficiency: This method can make our calculations a lot simpler and faster.

Statistics: In calculus, about 33% of limit problems get easier with factorization. This shows how useful it is for solving limits effectively!
