suppose * = 2. then we have a quadratic of the form

which can easily be solved using the quadratic formula as

which is simplified as

From here you have one of two ways to go.
(1) if you have never been shown imaginary numbers, then say no solution.
(2) If you have been shown imaginary numbers, then say
,
