Step-by-step explanation:

For

a

x

2

+

b

x

+

c

=

0

, the values of

x

which are the solutions to the equation are given by:

x

=

b

±

b

a

c

2

a

The discriminate is the portion of the quadratic equation within the radical:

b

2

4

a

c

If the discriminate is:

- Positive, you will get two real solutions

- Zero you get just ONE solution

- Negative you get complex solutions

To find the discriminant for this problem substitute:

9 for a

6 for b

1 for c

6

2

(

4

9

1

)

0

Because the Discriminant is

0

there is just ONE solution for this equation.
