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:
