PLEASE HELP ME FACTOR COMPLETLEY.

That is the difference of two squares. Remember that a^2 - b^2 = (a+b)(a-b)
Think of "a" as 5w and "b" as 12.
Now write down the answer.

No. Where did the w go?
They are asking for the expression
25w^2 - 144
to be factored, not evalauated.
The answer is
(5w + 12)(5w - 12)
