def quadratic(a,b,c):

import math

if b**2-4*a*c < 0:

return'该方程无解'

elif b**2-4*a*c == 0:

        x = -b/(2*a)

print('该方程只有一个解，该解为%-6.3f'%x)

else:

        x = (-b+math.sqrt(b**2-4*a*c))/(2*a)

        y = (-b-math.sqrt(b**2-4*a*c))/(2*a)

print('该方程有两个解，分别为%-6.3f和%-6.3f'%(x,y))

调用时报错

求助大佬指点！
