A quadratic equation is represented as ax2 + bx + c = 0
. The general formula to find its roots (x-values for which y = 0) is:
This formula provides two roots: x1, x2
. The value inside the square root, b2-4ac
is known as the discriminant (D
). Based on the value of the discriminant, a quadratic equation can have:
- two distinct real roots (
D > 0
); - one real root (
D = 0
); - no real roots (
D < 0
).
Your code must return a tuple containing two values: the roots x1, x2
, sorted descending. If there's only one real root, both values will be the same. If there are no real roots, the tuple should contain the string "No real roots"
.
Input: Three integers (number).

CheckiO Extensions allow you to use local files to solve missions. More info in a blog post.
In order to install CheckiO client you'll need installed Python (version at least 3.8)
Install CheckiO Client first:
pip3 install checkio_client
Configure your tool
checkio --domain=js config --key=
Sync solutions into your local folder
checkio sync
(in beta testing) Launch local server so your browser can use it and sync solution between local file end extension on the fly. (doesn't work for safari)
checkio serv -d
Alternatevly, you can install Chrome extension or FF addon
checkio install-plugin
checkio install-plugin --ff
checkio install-plugin --chromium
Read more here about other functionality that the checkio client provides. Feel free to submit an issue in case of any difficulties.
