Answer
(w+12)(w-12)
Work Step by Step
We use the formula for the difference of squares to apply to this question.
The difference of squares formula is:
$(a-b) (a+b) = a^{2} - b^{2}$
= $(w)^{2}$ - 144 *** Take the square root of 144 which is 12. Becuase 12 $\times$ 12= 144
= $(w)^{2} - 12^{2}$
In the given formula let w represents a and 144 represents b.
$(w)^{2} - 12^{2}$ = (w+12)(w-12)
