Calculate $\frac { \mathrm { d } y } { \mathrm {~d} x }$

Calculate $\frac { \mathrm { d } y } { \mathrm {~d} x }$ . You need not expand your answer. $y = \frac { 2 x + 2 } { 4 x - 5 }$

A) $\frac { 2 ( 4 x - 5 ) + 4 ( 2 x + 2 ) } { 4 x - 5 }$
B) $\frac { 2 ( 4 x - 5 ) - 4 ( 2 x + 2 ) } { ( 4 x - 5 ) ^ { 2 } }$
C) $\frac { 2 ( 4 x - 5 ) + 4 ( 2 x + 2 ) } { ( 4 x - 5 ) ^ { 2 } }$
D) $2 ( 4 x - 5 ) - 4 ( 2 x + 2 )$
E) 0.5
