Answer:

Step-by-step explanation:
First, extract the greatest common factor of the numerical as well as the variable parts:
the GCF of 5 and 80 is "5", and the GCF between
and
is
, then:

Now, we can re-write the binomial in parenthesis as a difference o squares to be able to factor out even further:

we now repeat the process for the binomial difference:

So finally the complete factorization is:
