Python Solve Quadratic Equation

Published on Apr 25, 2022

In this snippet, we will learn how to calculate the area of a triangle in Python.

Formula

Let's see the formula:

ax2 + bx + c = 0

Here a, b and c are real numbers and a ≠ 0.

Example

Now let's see an example:

import cmath

a = 1
b = 4
c = 9

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

sol1 = (-b-cmath.sqrt(d))/(2*a)
sol2 = (-b+cmath.sqrt(d))/(2*a)

print('The solution are: {0} and {1}'.format(sol1,sol2))

The output:

The solution are: (-2-2.23606797749979j) and (-2+2.23606797749979j)
