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.
- $f ( x ) = 2 x ^ { 4 } - 7 x ^ { 3 } + 15 x ^ { 2 } - 35 x + 25 ; c = 1$ is a zero

A) $- 5 , - 1 , \frac { 5 } { 2 } ; f ( x ) = ( x - 1 ) ^ { 2 } ( 2 x - 5 ) ( x + 5 )$
B) $\frac { 5 } { 2 } ; f ( x ) = ( x - 1 ) ( 2 x - 5 ) \left( x ^ { 2 } + 5 \right)$
C) $5 , \frac { 5 } { 2 } ; f ( x ) = ( x - 5 ) ( 2 x - 5 ) \left( x ^ { 2 } + 1 \right)$
D) $- 5 , - 1 , - \frac { 5 } { 2 } ; f ( x ) = ( x - 1 ) ( 2 x + 5 ) ( x + 1 ) ( x + 5 )$
