Perform the indicated operation.
-$$( 3 a - 8 b ) ( 3 a + 8 b )$$
A) $9 a ^ { 2 } - 64 b ^ { 2 }$
B) $6 a ^ { 2 } - 48 a ^ { 2 } - 16 b ^ { 2 }$
C) $6 a ^ { 2 } - 16 b ^ { 2 }$
D) $9 a ^ { 2 } - 48 a b - 64 b ^ { 2 }$

Quizplus · Accepted Answer

This is an application of the difference of squares formula, $a^2 - b^2 = (a - b)(a + b)$. Here, $a = 3a$ and $b = 8b$, so the product is $(3a)^2 - (8b)^2 = 9a^2 - 64b^2$.

Perform the Indicated Operation (3a−8b)(3a+8b)( 3 a - 8 b ) ( 3 a + 8 b )(3a−8b)(3a+8b)

Perform the Indicated Operation $( 3 a - 8 b ) ( 3 a + 8 b )$
