求助：這樣寫為什么不對？
import math
def quadratic_equation(a, b, c):
? ? x1 = -b+math.sqrt(b*b-4*a*c)/(2*a)
? ? x2 = -b-math.sqrt(b*b-4*a*c)/(2*a)
? ? return x1,x2
print quadratic_equation(2, 3, 0)
print quadratic_equation(1, -6, 5)

? ? return x1,x2

你的-b+math.sqrt(b*b-4*a*c)和下面那個都要用括號括起來，你這樣根據運算法則是先算后面再算前面的

嗷嗷。。。當時一定是傻了。。謝謝！
