- $$f ( x ) = 4 x ^ { 3 } - 8 x ^ { 2 } - x + 2$$

A) $1 , - 1,2 ; f ( x ) = ( 2 x - 1 ) ( 2 x + 1 ) ( x - 2 )$
B) $\frac { 1 } { 2 } , - \frac { 1 } { 2 } , 2 ; f ( x ) = ( 2 x - 1 ) ( 2 x + 1 ) ( x$
C) $2 , - 2,2 ; f ( x ) = ( x - 2 ) ( x + 2 ) ( x - 2 )$
D) $\frac { 1 } { 2 } , - \frac { 1 } { 2 } , 2 ; f ( x ) = ( x - 2 ) ( x + 2 ) ( x$
