Solving Quadratic Equation in easiest way using Python

image source
Python is a high-level programming language that is very simple and easy to learn yet powerful. It has efficient high-level data structures and a simple but effective approach to object-oriented programming. The Python interpreter and the extensive standard library can be downloaded at https://www.python.org/
This tutorial aims to solve quadratic equation in easiest way.

What Will I Learn?

Write here briefly the details of what the user is going to learn in a bullet list.

• Solving Quadratic Equation using Python
• Used of cmath module

Requirements

• Python IDLE

Difficulty

• Basic

Tutorial Contents

The Code:

First, import the cmath module which is already a package from the interpreter. This provides access to mathematical functions for complex numbers and it accepts integers, floating-point numbers or complex numbers as arguments.

import cmath

Second, take the coefficients a, b, and c from the user. It is treated as floating-point numbers so that it can accept non-decimal integers.

a = float(input('Enter value of a: '))
b = float(input('Enter value of b: '))
c = float(input('Enter value of c: '))

Third, calculate the discriminant with the formula b^2 - 4ac and assign it to a variable. In my case i used variable d.

d = (b**2) - (4*a*c)

Then with the discriminant value we can get our two solutions that can be solve using the formula x1 = -b+√(discriminant value) / 2a and x2 = -b-√(discriminant value) / 2a

solution1 = (-b-cmath.sqrt(d))/(2*a)
solution2 = (-b+cmath.sqrt(d))/(2*a)

And lastly, we print the answers of the solution.

print('The solution are {0} and {1}'.format(solution1,solution2))

Save the file and we can now run the code. Just press F5. The result will look like this:

This is my first contribution of an application using Python.

Thanks for reading! Hope you learn something.
