Please check my code because my coding play ground is not working. Topic- Solve Quadratic equation

Question

import cmath

a = 1
b = 5
c = 6

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

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

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

Answer 1

What's the problem ?
it gives solution -2 & -3

Answer 2

Actually, my coding play ground isn't working

Answer 3

Is it correct
