This is an example of the difference of squares formula, $a^2 - b^2 = (a + b)(a - b)$. Here, $a = p$ and $b = 13q$, so the product is $p^2 - (13q)^2 = p^2 - 169q^2$.

Multiply -(P + 13q)(p - 13q) A) p2−169q2p ^ { 2 } - 169 q ^ { 2 }p2−169q2

Multiply
-(P + 13q)(p - 13q)
A) $p ^ { 2 } - 169 q ^ { 2 }$
