2. Solve Quadratic Equations

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

# import complex math module

import cmath

a = int(input("Enter the value of a:"))

b = int(input("Enter the value of b:"))

c = int(input("Enter the value of c:"))

# calculate the discriminant

d = (b**2) - (4*a*c)

if d>0:

# find two solutions

r1 = (-b-cmath.sqrt(d))/(2*a)

r2 = (-b+cmath.sqrt(d))/(2*a)

print('The real roots are {0} and {1}'.format(r1,r2))

elif d==0:

r1 = -b/(2*a)

r2 = -b/(2*a)

print('The roots are equal {0} and {1} '.format(r1,r2))

else:

print('The roots are imaginary')
