There are multiple methods for solving quadratic equations, and here we practice identifying which method might be best to use in different cases. Of course, as you practice, you'll develop a preference for one method over another, and while you often have a choice, there are some problems that can only be solved using certain methods. The quadratic formula is a lot of work, but can be applied to any problem. Factoring is often the fastest, but can't always be used. If the "b" term is zero, consider isolating the x^2 term and then taking square roots of both sides (but remember to use both the +, - square roots!)
