Given a general quadratic equation of the form. You can enter the known values a b and c right away into the formula. In elementary algebra the quadratic formula is a formula that provides the solutions to a quadratic equationThere are other ways of solving a quadratic equation instead of using the quadratic formula such as factoring direct factoring grouping AC method completing the square graphing and others. In mathematics these tasks often take the form of common and important equations---for example the quadratic formula used to find the roots or zeroes of a quadratic equation---the points where it crosses the x-axis.
