The quadratic formula is necessary when the given quadratic equation can not be factored. If it can be factored, there is a new method, called the Diagonal Sum Method, that can quickly give the 2 roots in the form of 2 fractions. The concept of this method is finding 2 fractions, knowing their Sum (-b/a) and their Product (c/a). It is faster and more convenient than the trial-and-error factoring method since it works with fewer permutations, and it is always applicable whenever the equation can be factored.
