Comments: I enjoyed going back to my algebra days. It has been a while since I reviewed quadratic equations and had to do some googling. Overall, I did not run into much trouble with the prompts.

For the second question I kept putting x/y instead of x/n, but I resolved the issue after some mental focusing. 

Question: How can I prevent the "none" at the end of the incDenominator script? I resolved the issue. I was printing a print.

import math


def quadraticroots(a, b, c):
    # calculate discriminant
    discriminant = b ** 2 - 4 * a * c
    # plus minus sign
    fancysym = u"\u00B1"
    # calculates roots based off of discriminant
    if discriminant > 0:
        print(f"The roots are: {(-b + math.sqrt(discriminant)) / (2 * a)} , {(-b - math.sqrt(discriminant)) / (2 * a)}")
    elif discriminant == 0:
        print(f"The roots is: {(-b + math.sqrt(discriminant)) / (2 * a)}")
    else:
        rp = -b / (2 * a)
        ip = math.sqrt(abs(discriminant)) / (2 * a)
        print(f"The roots are: {rp} {fancysym} {ip}i")


quadraticroots(1, -5.86, 8.5408)
quadraticroots(1, -4, 4)
quadraticroots(1, 2, 5)

The roots are: 3.1400000000000006 , 2.7199999999999998
The roots is: 2.0
The roots are: -1.0 ± 2.0i

def incDenominator(x):
    if x > 0:
        y = range(1, 11)
        for n in y:
            print(x/n)
z = incDenominator(1)
print(z)
