The equation is .

Add 5 to each side.

Compare the equation with .

a = 9, b = and c = 1

a) Now we can find discriminant value

     (Substitute a = 9, b = and c = 1)

= 0                                             (Simplify)

b) The discriminant is positive, so the equation have two rational roots.

c) Apply quadratic formula:

        (Replace , a with 9, and b with )

Product of two same sings is positive.

The solution is .

The discriminant value is 0 and the equation have one rational root.

The solution is .
