## anonymous 5 years ago How do the principle of square roots is used to solve quadratic equations. What form must a quadratic equation be in to use the principle of square roots for solving? I also need help with an example...not sure how to accomplish this...

$ax^2+bx+c = 0$ to find values of "x" , use quadratic formula:$roots = {-b \pm \sqrt{b^2 - 4ac} \over 2a}$
