5.which statement below best describes how you would factor this polynomial completely? 3x2 - 75
select one:
a. take out the gcf. nothing else can be done.
b. take out the gcf, then factor the difference of squares.
c. there is no gcf, so factor the trinomial. one of the factors is a difference of squares, so factor it further.
d. take out the gcf, then factor the difference of squares. one of the factors is a difference of squares, so factor it further.
