Answer:
Step-by-step explanation:

We have to find the factors of 120 that can either add up to or have a difference of 2.
The factors of 120 are:

The difference of 10 and 12 is 2. In the equation, since the 2 is negative, the larger number must be subtracted, so the factorized form is:

Answer:
B is the wrong way, If it were correct it would be 31 14/29
K/6+8=5 C/2+5=1
K/6=-3 C/2=-4
K=-18 C=-8
9+A/6=8 D/4-9=-3
A/6=-1 D/4=6
A=-6 D=24
