Python Writing Quadratic Formula

Python Writing Quadratic Formula

I want to try and make my print function automatically substitute the
variable 'a' 'b' and 'c' with one of the values assigned to those
variables in my tests. How would I do this? My ideal output would look
like this Equation: 1x**2 + 4x + 4 One root. 2.0
import math
def quadraticRoots(a,b,c):
print('Equation: ax**2 + bx + c') # (this is what I am trying and
it doesn't work)
discriminant = b**2 - 4 * a * c
if discriminant > 0:
root1 = float(-b + math.sqrt(b**2 - 4 * a * c))/ (2 * a)
root2 = float(-b - math.sqrt(b**2 - 4 * a * c))/ (2 * a)
print('Two roots.')
print(root1)
print(root2)
elif discriminant == 0:
root1 = float(-b + math.sqrt(b**2 - 4 * a * c))/ (2 * a)
print('One root.')
print(root1)
elif discriminant < 0:
print('No roots.')
