the answer is (w-5)(w+5)(w^2+25)

Explanation:

since this is two difference of two squares, the square root of 4 is 2 and 25*25 will give you 625 but now, one of your answers is still a difference of squares(w^2-25) so now you have to simplify it further into: (w-5)(w+5) then just add the other one into it to get your answer
