Quadratic Equation

This program calculates the roots of a quadratic equation from the co-efficient a, b and c. This program also calculates the roots if they are imaginary.

Code:

	import math
	print("Enter the co-efficient of quadratic equation.")
	a = float(input("Enter a:"))
	b = float(input("Enter b:"))
	c = float(input("Enter c:"))
	d = b**2 - 4*a*c
	if d < 0:
	real = -b/(2*a)
	imag = math.sqrt(-d)/(2*a)
	root1 = complex(real,imag)
	root2 = complex(real,-imag)
	print('The roots are complex:')
	print(root1)
	print(root2)
	elif d == 0:
	root = -b/(2*a)
	print('The roots are equal:')
	print(root)
	else:
	root1 = (-b + math.sqrt(d))/(2*a)
	root2 = (-b - math.sqrt(d))/(2*a)
	print('The roots are real:')
	print(root1)
	print(root2)
