Quadratic Equation Solver: Type the coefficients of your quadratic equation into the box to get a solution with the steps. If there is not a coefficient in front of your x^2, simply use 1. To better understand the methods please read below!

A quadratic equation is any equation where the highest degree term (the term with the largest exponent) is a variable to the 2nd power.  These equations can always be written in the form:

where a, b and c are real numbers and a can not be zero. Of course a lot of the time a quadratic equation you come across may not look like this at all. The idea is that is can be simplified in some way to look like the equation above .

There are many ways to solve quadratic equations, so each is given its own seperate article. You should take the time to know ALL of these methods!
