The equation is .
Compare the equation with .
a = 3, b = and c = 2.
a) Now we can find discriminant value
\ (Substitute a = 3, b =
and c = 2)
b) The discriminant is positive, so the equation have two rational roots.
\c) Apply quadratic formula:
(Replace
, a with 3, and b with
)
Product of two same sings is positive.
The solutions are .
The discriminant value is 12 and the equation have two complex roots.
\The solutions are .
