Answer:
n = (1/2)(-1 ± i√2)
Step-by-step explanation:
Among the several ways in which quadratic equations can be solved is the quadratic formula.  Putting to use the coefficients {12, 12, 9}, we obtain the discriminant, b^2 - 4ac:  12^2 - 4(12)(9) = 144 - 432 = -288.  The negative sign of this discriminant tells us that the quadratic has two unequal, complex roots.  These roots are:
       -b ± √(discriminant)
n = ---------------------------------
                  2a
Here we have:
       -12 ± √(-288)           -12 ± i√2√144          -12 ± i12√2
n = ----------------------  =  ------------------------ =  --------------------
             2(12)                             24                           24
or:
n = (1/2)(-1 ± i√2)
