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

Quizplus · Accepted Answer

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

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

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