A) $x ^ { 2 } - 24 x y - 144 y ^ { 2 }$
B) $x ^ { 2 } - 144 y ^ { 2 }$
C) $x ^ { 2 } - 24 y ^ { 2 }$
D) $x ^ { 2 } + 24 x y - 144 y ^ { 2 }$

This is an application of the difference of squares formula, $a^2 - b^2 = (a + b)(a - b)$, where $a = x$ and $b = 12y$. So, $(x + 12y)(x - 12y) = x^2 - (12y)^2 = x^2 - 144y^2$.

Multiply - (x+12y)(x−12y)( x + 12 y ) ( x - 12 y )(x+12y)(x−12y)

Multiply
- $( x + 12 y ) ( x - 12 y )$
