Python Program to solve quadratic equation
'''
Solve the quadratic equation ax**2 + bx + c = 0
ax2 + bx + c = 0, where
a, b and c are real numbers and
a ≠ 0
'''
#import complex math module
import cmath
a = 1
b = 5
c = 6
#To take coefficient input from the users
a, b and c are real numbers and
a ≠ 0

a = 1
b = 5
c = 6
#To take coefficient input from the users
#a = float(input('Enter a: '))
#b = float(input('Enter b: '))
#c = float(input('Enter c: '))
#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
>>>
The solution are (-3+0j) and (-2+0j)
