Quadratic Equation in Python

a = float(input("Enter a: "))
b = float(input("Enter b: "))
c = float(input("Enter c: "))

if(math.pow(b,2) -  (4*a*c) >= 0):
    x_1 = (-b  + math.sqrt(math.pow(b,2) -  (4*a*c)))/(2*a)
    x_2 = (-b  - math.sqrt(math.pow(b,2) -  (4*a*c)))/(2*a)
    print("x1 {}  and x2 {}".format(x_1,x_2))
else:
    print("The root of the equation are imaginary numbers")
