Multiple Choice

Find the derivative of the function.
- y=(x10) (x2+4x) x3y = \frac { ( x - 10 ) \left( x ^ { 2 } + 4 x \right) } { x ^ { 3 } }


A) dydx=x80x280x3\frac { d y } { d x } = x - \frac { 80 } { x ^ { 2 } } - \frac { 80 } { x ^ { 3 } }
B) dydx=6x2+80x3\frac { d y } { d x } = \frac { 6 } { x ^ { 2 } } + \frac { 80 } { x ^ { 3 } }
C) dydx=14x280x3\frac { d y } { d x } = \frac { 14 } { x ^ { 2 } } - \frac { 80 } { x ^ { 3 } }
D) dydx=80+80x\frac { \mathrm { dy } } { \mathrm { dx } } = 80 + \frac { 80 } { \mathrm { x } }
