Find the partial fraction decomposition for the rational expression.
- $$\frac { 12 x ^ { 2 } - 23 x + 20 } { ( x - 4 ) \left( x ^ { 2 } + 4 \right) }$$

A) $\frac { - ( 6 x + 1 ) } { x ^ { 2 } + 4 } + \frac { 6 } { x - 4 }$
B) $\frac { 6 x + 1 } { x ^ { 2 } + 4 } + \frac { 6 } { x - 4 }$
C) $\frac { 6 x - 1 } { x ^ { 2 } + 4 } + \frac { - 6 } { x - 4 }$
D) $\frac { 6 x + 6 } { x ^ { 2 } + 4 } + \frac { 1 } { x - 4 }$
