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)
