Write Quadratic Equation
Quadratic Equation
may be expressed as a product
a(x-x1)(x-x2) = 0,where x1 and x2 are the solutions of equation, so called roots. After opening the brackets you receive well known form
a*x**2 + b*x + c = 0.This is what you should do in this mission. You have input list with integers - a, x1 [, x2]. If it has length 2, it means, x1 == x2: equation has two equal roots (one distinct root). Your function should return quadratic equation as a string. Pay attention to specific cases. Use Quadratic Formula Calculator for recheck. Good luck!
Input: List with 2-3 integers.
Output: String.
Examples:
assert quadr_equation([2, 4, 6]) == "2*x**2 - 20*x + 48 = 0" assert quadr_equation([-2, 4, 6]) == "-2*x**2 + 20*x - 48 = 0" assert quadr_equation([2,...
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=py 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.
