Essential Question: How do you use the quadratic formula and the discriminant? Students will write a summary including the steps for using the quadratic formula and how it applies to the discriminant. The Discriminant The part under the radical sign of the quadratic formula is called the discriminant. By calculating the discriminant, you can determine how many and what type of solutions an equation will have.
