would anyone mind explaining the quadratic formula for me ?

critical  Oct 3, 2018

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 !

Yes, it's in the form \(ax^2+bx+c\), and you plug the values into this formula: \(x = {-b \pm \sqrt{b^2-4ac} \over 2a}\). Neat that web2.0calc gives you the quadratic formula, when you press the latex button! Remember that, \(\pm\) is plus or minus.
