You forgot a very important pair of steps.


Step 1:  Multiply the lead coefficient by the constant term.


Step 2:  Find a pair of factors of the result whose sum is the first degree term coefficient, and then divide the first degree term there.


4 times 12 is 48.  You want to find a + b = 19 where ab = 48.
