Tutorials: The Discriminant

1. 1. The Discriminant
2. 2. Overview This set of tutorials provides 10 examples of finding the determinant of a quadratic equation to determine the number of real roots.
3. 3. Tutorial--Calculating the Determinant: Example 1. In this example a, b, and c are positive, discriminant is positive.
4. 4. Tutorial--Calculating the Determinant: Example 2. In this example a, b, and c are positive, discriminant is negative
5. 5. Tutorial--Calculating the Determinant: Example 3. In this example a, b, and c are positive, discriminant is zero
6. 6. Tutorial--Calculating the Determinant: Example 4. In this example a, b, and c are negative, discriminant is positive.
7. 7. Tutorial--Calculating the Determinant: Example 5. In this example a, b, and c are negative, discriminant is negative.
8. 8. Tutorial--Calculating the Determinant: Example 6. In this example a, b, and c are negative, discriminant is zero.
9. 9. Tutorial--Calculating the Determinant: Example 7. In this example a is positive and b and c are negative, discriminant is positive. Point out to students that in this configuration the discriminant can only be positive.
10. 10. Tutorial--Calculating the Determinant: Example 8. In this example a and b are positive and c is negative, discriminant is positive. Point out to students that in this configuration the discriminant can only be positive.
