System.out.println("Roots are real and unequal");

                       if (d == 0)

             Output:
             Enter the value of a

             2
             Enter the value of b
             3
             Enter the value of c
             -2
             Roots are real and unequal
             First root is 0.5
             Second root is -2.0

             * * * * \
             * * * \ *
             * * \ * *
             * \ * * *
