It is a way to solve quadratic equations .
When you have a quadratic equation of the form a x^2 + b x + c = 0 you can use the quadratic formula to find the solutions to the equation.
The Quadratic Formula is:
\(x = {-b \pm \sqrt{b^2-4ac} \over 2a}\) Substitute for 'a' 'b' and 'c' to find the solutions !
