1036.Bhaskara's Formula in python

This is the solution of this problem:

import math
a,b,c=input().split()
a = float(a)
b = float(b)
c = float(c)
d = float(b*b)-(4*a*c)
if(a!=0):
    d = (b*b)-(4*a*c)
    if(d>0):
        x1 = (-b+math.sqrt(d))/(2*a)
        x2 = (-b-math.sqrt(d))/(2*a)
        print("R1 = %.5f"%x1)
        print("R2 = %.5f"%x2)
    else:
        print("Impossivel calcular")
       
else:
    print("Impossivel calcular")
