Find the Remaining Zeros of F(x)given That C Is a Zero

Multiple Choice

Find the remaining zeros of f(x) given that c is a zero. Then rewrite f(x) in completely factored form.
- $f ( x ) = x ^ { 4 } + 12 x ^ { 2 } - 64 ; c = 2$ is a zero

A) $2 ; f ( x ) = ( x - 2 ) ^ { 2 } \left( x ^ { 2 } + 16 \right)$
B) $- 2 , - 4,4 ; f ( x ) = ( x - 2 ) ( x + 2 ) ( x - 4 ) ( x + 4 )$
C) $- 2 ; f ( x ) = ( x - 2 ) ( x + 2 ) \left( x ^ { 2 } + 16 \right)$
D) $- 4 ; f ( x ) = ( x - 4 ) ( x + 4 ) \left( x ^ { 2 } + 4 \right)$
