The Quadratic Formula

Quadratic formulas can be easily factored by completing the square, but that is only if the middle term (b term) is even. However, what if the middle term is not even and the quadratic is not factorable. This is when the quadratic formula comes in. For this formula all you have to do is identify the values of a, b, and c in standard form equation and then sub them into the quadratic formula.
