The equation is .

Subtract 5 from each side.

Compare the equation with .

a = 1, b = 3 and c = 3

a) Now we can find discriminant value

        (Substitute a = 1, b = 3 and c = 3)

.

b) The discriminant is negative, so the equation have two complex roots.

The discriminant value is and the equation have two complex roots.
