Hope this helps you out.

Answer 2

`6(3m-2)`

Explanation:

we have the expression:

`18m - 12`

and we can express the number 18 by its factors like this:

`18=6*3`

and also the number 12:

`12=6*2`

so in both numbers we have a common factor of 6:

`6*3m-6*2`

So we can factor the given expression by taking out the 6 of each coefficient, and we get the following:

`6(3m-2)`

which is the fourth option.
