Solve the problem.
-$( 4 y + x ) ( 4 y - x )$
A) $16 y ^ { 2 } + 8 x y - x ^ { 2 }$
B) $16 y ^ { 2 } - 8 x y - x ^ { 2 }$
C) $8 y ^ { 2 } - x ^ { 2 }$
D) $16 y ^ { 2 } - x ^ { 2 }$

Question

Quizplus · Accepted Answer

This problem uses the difference of squares formula, $a^2 - b^2 = (a + b)(a - b)$. Here, $a = 4y$ and $b = x$, so the expression simplifies to $16y^2 - x^2$.

Solve the Problem (4y+x)(4y−x)( 4 y + x ) ( 4 y - x )(4y+x)(4y−x)
