Python Program to Solve Quadratic Equation using cmath Module

The cmath module in python makes the work easier with the pre-built functions. In the below program we are using cmath module for the calculations.

Program:

# Python program to find roots of quadratic equation

#importing cmath module
import cmath  

# inputs from user
a = float(input('Enter the value of a: '))
b = float(input('Enter the value of b: '))
c = float(input('Enter the value of c: '))

# calculate discriminant
dis = (b**2) - (4*a*c)

# find roots of quadratic equation
root1 = (-b-cmath.sqrt(dis))/(2*a)
root2 = (-b+cmath.sqrt(dis))/(2*a)

# print result
print('The roots are {0} and {1}'.format(root1,root2))

Output:

Enter the value of a: 1
Enter the value of b: 4
Enter the value of c: 5
The roots are (-2-1j) and (-2+1j)
