Quadratic Equation Solver

If you have an equation of the form ax^2 + bx + c = 0, I can solve it for you.

How to use:

In a file there is a function

get_roots(a, b, c)

Input: It takes 3 numbers - coefficiens a, b, c from the formula

ax^2 + bx + c = 0

Output: Discriminant = b^2 − 4ac

• two roots: (x1, x2) - if discriminant > 0
• one root, None: (x1, None) - if discriminant == 0
• None, None: (None, None) - if discriminant < 0

How to launch:

You need pre-installed Python 3.5 of higher

Usage Example:

#import the function
from quadratic_equation import get_roots

a, b, c = map(int, input().split())
x1, x2 = get_roots(a, b, c)
print(x1, x2)

Unit Testing:

Testing with Python's unittest module. unittest- Automated testing framework

Example of script launch on Linux, Python 3.5::

python tests.py
