factoring is mostly guess and check at least for me and its reverse FOIL so if you think of it that way you can find some numbers whos product is 8 (4 and 2) and another pair of numbers whos product is 9 (3 and 3) and the sum of the product of one of each pair to one of the other pair is 18 (3*2 + 3*4)
