Answer:
can be factored out as: 
Step-by-step explanation:
Recall the formula for the perfect square of a binomial :

Now, let's try to identify the values of
and
in the given trinomial.
Notice that the first term and the last term are perfect squares:

so, we can investigate what the middle term would be considering our
, and
:

Therefore, the calculated middle term agrees with the given middle term, so we can conclude that this trinomial is the perfect square of the binomial:

Scale factor is 1/3
And I think it's an enlargement
