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

	# import complex math module
	import cmath

	a = 1
	b = 4
	c = 5

	# 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 is :

	The solution are (-2-1j) and (-2+1j)
