Python：根据用户输入求解一元二次方程的实数解

```python import math a = float(input()) b = float(input()) c = float(input()) delta = b 2 - 4 * a * c if delta < 0: print("no real roots!") else: x1 = (-b + math.sqrt(delta)) / (2 * a) x2 = (-b - math.sqrt(delta)) / (2 * a) if x1 > x2: print("{:.2f} {:.2f}".format(x1, x2)) else: print("{:.2f} {:.2f}".format(x2, x1)) ``` ######[AI写代码神器 | 246点数解答 | 2024-10-15 23:16:11]
