The Discriminant and the quadratic formula
Find the discriminant for each quadratic equation. State the number of real roots and then find the real solution(s), if any exist.
1. x2 - 6x + 5 = 0
2. 2x2 - 4x - 6 = 0
3. 3x + 4x2 + 5 = 0
4. 6x – 9 = x2
5. 3x2 = 6x – 8
6. 4x2 - 9x – 2= 0
7. x (2x – 5) = 10
8. What is the relationship between the discriminant of a quadratic and its graph?
