求解一元二次方程方程代码python

在Python中，你可以使用内置的`cmath`模块（对于复数求解）或`math`模块（仅限于实数解）来求解一元二次方程。一元二次方程通常的形式是 ax^2 + bx + c = 0。下面是一个简单的示例，展示如何使用公式法来求解实数解：

import math

def solve_quadratic_equation(a, b, c):
    # 计算判别式
    discriminant = b**2 - 4*a*c
    
    # 实数解的情况
    if discriminant >= 0:
        x1 = (-b + math.sqrt(discriminant)) / (2 * a)
        x2 = (-b - math.sqrt(discriminant)) / (2 * a)
        return x1, x2
    # 复数解的情况
    else:
        real_part = -b / (2 * a)
        imaginary_part = math.sqrt(-discriminant) / (2 * a)
        return complex(real_part, imaginary_part), complex(real_part, -imaginary_part)

# 示例：求解方程x^2 + 5x + 6 = 0
a = 1
b = 5
c = 6
solutions = solve_quadratic_equation(a, b, c)
print("解为:", solutions)
