Perform the Indicated Operation $\frac { 2 x } { x ^ { 2 } - 16 } - \frac { 3 } { x ^ { 2 } - 5 x + 4 } + \frac { x + 1 } { x ^ { 2 } + 3 x - 4 }$

Multiple Choice

Perform the indicated operation. Simplify, if possible. $\frac { 2 x } { x ^ { 2 } - 16 } - \frac { 3 } { x ^ { 2 } - 5 x + 4 } + \frac { x + 1 } { x ^ { 2 } + 3 x - 4 }$

A) $\frac { 3 x + 4 } { ( x + 4 ) ( x - 1 ) }$
B) $\frac { 3 x } { ( x + 4 ) ( x - 4 ) ( x - 1 ) }$
C) $\frac { 3 x ^ { 2 } - 4 x } { ( x + 4 ) ( x - 4 ) ( x - 1 ) }$
D) $\frac { 3 x ^ { 2 } - 2 x - 4 } { ( x + 4 ) ( x - 4 ) ( x - 1 ) }$
