## Quadratic Formula

Summary

The Quadratic Formula is a critical tool for solving quadratic equations that cannot be factored or easily solved by completing the square, especially in the context of the SAT exam.

- The Quadratic Formula is applicable for equations that cannot be factored and do not fit neatly into algebraic patterns.
- It is essential to convert the quadratic equation into standard form before applying the Quadratic Formula.
- The discriminant (b squared minus 4ac) under the radical sign in the formula determines the nature of the roots (real or imaginary).
- The SAT will provide the Quadratic Formula, so memorization is not necessary.
- Completing the square is an alternative method that can sometimes offer a quicker solution.
