Python Program to Solve Quadratic Equation

# Solve the quadratic equation  ax**2 + bx + c = 0

#import complex math module 
import cmath

a = 1
b = 5
c = 6

# To take coefficient input from the users
# a = float (input ('Enter a: ' ))
# b = float (input ('Enter a: ' ))
# c = float (input ('Enter a: ' ))

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

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

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

Output

Enetr a: 1
Enetr b: 5
Enetr c: 6
The solution are (-3+0j) and (-2+0j)
