Answer:
You are trying to find the common factors/like terms that can be divided from the expression.
12x - 15y + 6
Every term in this expression can be divided by 3.
= 3 · 4x - 3 · 5y + 3 · 2
Since all of these terms can be divided by 3, 3 in this case, is our common factor/like term.
So our answer will just be:
= 3(4x - 5y + 2).
