為什么不對

import math def quadratic_equation(a, b, c): ? d=b*b-4*a*c ? ?if d>= 0: ? ?x1 = (-b+math.sqrt(d))/(2*a) ? ?x2 = (-b-math.sqrt(d))/(2*a) ? ?return x1,x2 ? ?else: ? ? ? ?return ? ? print quadratic_equation(2, 3, 0) print quadratic_equation(1, -6, 5) 為什么提示不正確

??? d=b*b-4*a*c
??? if d>= 0:
??????? x1 = (-b+math.sqrt(d))/(2*a)
??????? x2 = (-b-math.sqrt(d))/(2*a)
??????? return x1,x2
??? else:
??????? return
print quadratic_equation(2, 3, 0)
print quadratic_equation(1, -6, 5)

是否是因為縮進導致的？我運行你的代碼有結果。
