Find the product.
-$$( p + 7 q ) ( p - 7 q )$$
A) $p ^ { 2 } - 14 q ^ { 2 }$
B) $p ^ { 2 } - 14 p q - 49 q ^ { 2 }$
C) $p ^ { 2 } + 14 p q - 49 q ^ { 2 }$
D) $p ^ { 2 } - 49 q ^ { 2 }$

This is an application of the difference of squares formula, $a^2 - b^2 = (a + b)(a - b)$. Here, $a = p$ and $b = 7q$, so the product is $p^2 - (7q)^2 = p^2 - 49q^2$.

Find the Product (p+7q)(p−7q)( p + 7 q ) ( p - 7 q )(p+7q)(p−7q)

Find the Product $( p + 7 q ) ( p - 7 q )$
