Answer:
Case 1: a = 1.5, b = 2, c = -3
Case 2: a = 2.3, b = -4, c = 1
Case 3: a = 3.7, b = 9, c = -4
Case 4: a = 4.6, b = -8, c = 5
Case 5: a = 5.5, b = 7, c = -3
Case 6: a = 6.9, b = -5, c = 2
Case 7: a = 7.2, b = 6, c = -4
Case 8: a = 8.3, b = -3, c = 4
Case 9: a = 9.9, b = 4, c = -7
Case 10: a = 10.4, b = 8, c = -5
Step-by-step explanation:
For all second order polynomial, the discriminant is equal to:
Case 1: a = 1.5, b = 2, c = -3
Case 2: a = 2.3, b = -4, c = 1
Case 3: a = 3.7, b = 9, c = -4
Case 4: a = 4.6, b = -8, c = 5
Case 5: a = 5.5, b = 7, c = -3
Case 6: a = 6.9, b = -5, c = 2
Case 7: a = 7.2, b = 6, c = -4
Case 8: a = 8.3, b = -3, c = 4
Case 9: a = 9.9, b = 4, c = -7
Case 10: a = 10.4, b = 8, c = -5
