Using the Factors $( x + 4 )$ And $( x + 3 )$

Multiple Choice

Using the factors $( x + 4 )$ and $( x + 3 )$ , find the remaining factor(s) of $f ( x ) = x ^ { 3 } + 6 x ^ { 2 } + 5 x - 12$ and write the polynomial in fully factored form.

A) $f ( x ) = ( x + 4 ) ( x + 3 ) ( x - 1 )$
B) $f ( x ) = ( x + 4 ) ( x + 3 ) ^ { 2 }$
C) $f ( x ) = ( x + 4 ) ( x + 3 ) ( x + 1 )$
D) $f ( x ) = ( x + 4 ) ^ { 2 } ( x + 3 )$
E) $\quad f ( x ) = ( x + 4 ) ( x + 3 ) ( x + 3 )$
