Quadratic Formula: an equation which the highest power of an unknown quality is a square! This is to solve for the roots or zeros of the quadratic equation!

ax2+bx+c=0

+The simplest way to solve this general equation to find the value of x is the factor the quadratic.

+Set each factor equal to zero and then solve each factor.

+You use the a, b and c of this formula to plug into the like variable in the quadratic formula!

+This Quadratic formula can always find the solution!

+Never try and take a short cut through this because it will get all messed up and the answer will be wrong, so take your time!

+This equation is used to compute the roots of a quadratic.
