Multiply the polynomials using a special product formula. Express the answer as a single polynomial in standard form.
-$$( 13 x + 11 ) ( 13 x - 11 )$$
A) $x ^ { 2 } - 121$
B) $169 x ^ { 2 } - 286 x - 121$
C) $169 x ^ { 2 } + 286 x - 121$
D) $169 x ^ { 2 } - 121$

This is an example of the difference of squares formula, $a^2 - b^2 = (a + b)(a - b)$, where $a = 13x$ and $b = 11$. Thus, the product is $169x^2 - 121$.
