def quadratic(a, b, c):

# 测试:
print('quadratic(2, 3, 1) =', quadratic(2, 3, 1))
print('quadratic(1, 3, -4) =', quadratic(1, 3, -4))

if quadratic(2, 3, 1) != (-0.5, -1.0):
    print('测试失败')
elif quadratic(1, 3, -4) != (1.0, -4.0):
    print('测试失败')
else:
    print('测试成功')

 Runquadratic(2, 3, 1) = (-2.0, -4.0)

quadratic(1, 3, -4) = (1.0, -4.0)

测试失败
