Okay so you split 9ab + 12ax - 6b - 8x
<span>             into two 2-term polynomials </span>
              + 12ax + 9ab   and     - 6b - 8x
             doesn't look that good to me so lest try other one :
             9ab + 12ax   and     - 6b - 8x
             looks good for now

<span>     </span>      Pull out from each binomial separately
             9ab + 12ax   =   3a • (3b + 4x)
              - 6b - 8x   =    - 2 • (3b + 4x)

<span>    </span>      Add up to arrive at the desired factorization so now you have
            <span> (3a - 2) • (3b + 4x)
