We use the formula for the difference of squares to apply to this question. The difference of squares formula is: $(a-b) (a+b) = a^{2} - b^{2}$ $p^{2} - 36$ We rewrite it in $a^{2} - b^{2}$ form $p^{2} - 6^{2}$ In the given formula let p represents a and 6 represents b. $a^{2} - b^{2}$ = (a-b) (a+b) $p^{2} - 6^{2}$ =(p-6)(p+6)
