A. Find the discriminant, and determine the nature of the roots.
1. x2 = 16x + 64
2. 3x² = 4x + 5
3. 2x2 = -3x - 1
4. 4x2 + 4x + 1 = 0
5. 4x2 + 4x + 3 = 0
6. x2 + 8x = -9
7. 7x2 = x + 3
8. 5x2 - 3x + 1 = 0
9. 3x2 + 3x - 2 = 5
10. x² + 3x - 2 = -1
1. x2 = 16x + 64
2. 3x² = 4x + 5
3. 2x2 = -3x - 1
4. 4x2 + 4x + 1 = 0
5. 4x2 + 4x + 3 = 0
6. x2 + 8x = -9
7. 7x2 = x + 3
8. 5x2 - 3x + 1 = 0
9. 3x2 + 3x - 2 = 5
10. x² + 3x - 2 = -1
