Purplemath — Your Algebra Resource This lesson may be printed out for personal use. Terms of (web)Use The Quadratic Formula - I Lessons Home Lesson pages: The Formula explained, The Discriminant: solutions and graphs The Formula explained Often, the simplest way to solve " ax bx c " for the value of x is to factor the quadratic , set each factor equal to zero, and then solve each factor. But sometimes the quadratic is too messy, or it doesn't factor at all, or you just don't feel like factoring. So, while factoring may not always be successful, the Quadratic Formula can always find the solution. The Quadratic Formula uses the " a ", " b ", and " c " from " ax bx c ", where " a ", " b ", and " c " are just numbers. The Formula is derived from the process of completing the square, and is formally stated as:

The generalized form is a x b x c y where a The letters a b and c are called coefficients a is the coefficient of x b is the coefficient of x , and c is the free term or constant. A quadratic equation with real or complex coefficients has two complex roots (i.e., solutions for x when y = 0) usually denoted as x and x , although the two roots may be equal. These roots can be computed using the
