If you recall the previous lessons, the methods are just applicable for a specific quadratic equation. For example, the process of “factoring” is appropriate only if the quadratic expression is factorable. But, do not worry because there is one process that is applicable for all forms of quadratic equations that will be tackled in this module.

**LEARNING COMPETENCY**

The learners will be able to:

- solve quadratic equations by:(d) using the quadratic formula.
