Solving Quadratic Equations – Part 2 Quadratic Formula - another way to solve quadratic equations based on the standard form for a quadratic equation It is used primarily for quadratics that CAN NOT be easily factored, but will work with ANY quadratic. I call it the “way that always works”.
Solving Quadratic Equations – Part 2 Quadratic Formula - another way to solve quadratic equations based on the standard form for a quadratic equation Here is the formula : Just a “heads up” here. It is possible to get answers here that are not integers or fractions. The answers could contain radicals that can not be simplified.

Solving Quadratic Equations – Part 2 Quadratic Formula - another way to solve quadratic equations based on the standard form for a quadratic equation Here is the formula : Just a “heads up” here. It is possible to get answers here that are not integers or fractions. The answers could contain radicals that can not be simplified. Also, you could get a negative under the radical when evaluating. If that happens, there is no solution because the square root of a negative is not possible.
