By the trial&error method, for 6x^2 - 11x + 4,
(6x + ?)(x +.... you know this one is no good.
(6x - ?)(x - ?)
(2x - ?)(3x - ?)

You get a product of 4 from any of these:
4=4*1=2*2

Are you saying that the factorization is (6x + 2)(x -2)? Whether you are or aren't, these aren't the factors of 6x^2 -11x + 4.

Try the AC method
6x^2-11x+4 coef for A=6; coef for c=4 product 6(4)=24;
find facors of 24 which can make 11 (3 and 8)
