写一个求解一元二次方程组的Python代码吧

好的，以下是求解一元二次方程组的Python代码：

import math

def solve_quadratic_equation(a, b, c):
    delta = b ** 2 - 4 * a * c
    if delta < 0:
        return None
    elif delta == 0:
        x = -b / (2 * a)
        return x
    else:
        x1 = (-b + math.sqrt(delta)) / (2 * a)
        x2 = (-b - math.sqrt(delta)) / (2 * a)
        return x1, x2

# 例子
a1, b1, c1 = 1, 2, -3
a2, b2, c2 = 2, -3, 1

x1, x2 = solve_quadratic_equation(a1, b1, c1)
print(f"x1={x1}, x2={x2}")

x1, x2 = solve_quadratic_equation(a2, b2, c2)
print(f"x1={x1}, x2={x2}")

希望能帮到你！
