-$12 z ^ { 2 } + 7 z y - 12 y ^ { 2 }$
A) $( 12 z - 3 y ) ( z + 4 y )$
B) $( 4 z + 3 y ) ( 3 z - 4 y )$
C) $( 12 z + y ) ( z - 12 y )$
D) $( 4 z - 3 y ) ( 3 z + 4 y )$

Question

The first term can be factored as $4z\cdot 3z$ and the last term can be factored as $4y\cdot (-3y)$. The middle term can then be factored as the product of the outer and inner terms of these two binomials, giving us $(4z-3y)(3z+4y)$.
