按照這個代碼，為什么結果出不來啊

>>> import math
>>> def quadratic_equation(a, b, c):
...???? t = math.sqrt(b * b - 4 * a * c)
...???? return (-b + t) / (2 * a),( -b - t )/ (2 * a)
...???? print quadratic_equation(2, 3, 0)
...???? print quadratic_equation(1, -6, 5)

>>>
>>>
>>>
>>>

一直回車，出不來答案

import?math
def?quadratic_equation(a,?b,?c):?????
????t?=?math.sqrt(b?*?b?-?4?*?a?*?c)?????
????return?(-b?+?t)?/?(2?*?a),(?-b?-?t?)/?(2?*?a)?????
print?quadratic_equation(2,?3,?0)
print?quadratic_equation(1,?-6,?5)

輸出結果
