The Quadratic Formula - Problem 10

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!)
