Unless I am failing to understand your problem, just combine like terms to get:
9x^2+2x+4 and then enter those coefficients into the quadratic solver.
That will get you the two answers -- both of them will be complex.
If you wanted to turn those two answers into factors (complex) of the original equation simply
change the signs on each and put an x in front.
Of course, the quadratic formula would also work.

SOURCE: I forgot how to do
Press [MODE]. In first column enter known x-coordinates (1 and 5), in second known y-coordinates (2 and 6). The solution you are looking for is in form Y=A+B*X where X=3. Your calculator computes A and B after you enter data. To calculate Y (which is equal to A+B*3 press [SHIFT][+][SHIFT][*][=]. The result should be 4.
