A) $11 a ^ { 2 } - 4 c ^ { 2 }$
B) $121 a ^ { 2 } - 88 a c - 16 c ^ { 2 }$
C) $121 a ^ { 2 } - 16 c ^ { 2 }$
D) $121 a ^ { 2 } + 88 a c - 16 c ^ { 2 }$

This is an application of the difference of squares formula, $a^2 - b^2 = (a + b)(a - b)$. Here, $a = 11a$ and $b = 4c$, so the product is $121a^2 - 16c^2$.

Find the Product (11a+4c)(11a−4c)( 11 a + 4 c ) ( 11 a - 4 c )(11a+4c)(11a−4c)
