Answer:
less thaan
Step-by-step explanation:
becuase you subtract 11 from the x values to get the answer.
We can change the sign of the second term, so that the two parenthesis are the same:

Now, both terms have in common a 3, becase the numeric factors are 3 and 6. If we factor the 3, we have

The parenthesis (a-1) is also in common, so we can factor it as well:

Finally, both terms in the parenthesis contain
, because it's the power of b with the lowest exponent:

So, the factorization is

You can swap the order of the four factors (3, b^2, a-1 and 2b-1) as you like: the multiplication is commutative.
