The quadratic formula is useful for when you cannot factor a quadratic equation into it's roots (since they are decimals or fractions). 

A standard quadratic equation is in this form; ax²+bx+c=0 

The quadratic function is [tex] \frac{-b+- \sqrt{b x^{2} -4ac} }{2a} [/tex]

Insert the values of a, b and c into this equation to find out the roots. 

Hope I helped :)
