(\partial)/(\partial x)(((2x-y))/(2x+y))

\frac{\partial}{\partial x} (\frac{( 2 x - y )}{2 x + y})

\frac{4 y}{( 2 x + y ) ^{2}}

Solution steps

\frac{\partial}{\partial x} (\frac{( 2 x - y )}{2 x + y})

Treat

y

as a constant

Apply the Quotient Rule:

(\frac{f}{g})^{'} = \frac{f ^{'} \cdot g - g ^{'} \cdot f}{g ^{2}}

= \frac{\frac{\partial}{\partial x} ( 2 x - y ) ( 2 x + y ) - \frac{\partial}{\partial x} ( 2 x + y ) ( 2 x - y )}{( 2 x + y ) ^{2}}

\frac{\partial}{\partial x} (2 x - y) = 2

\frac{\partial}{\partial x} (2 x + y) = 2

= \frac{2 ( 2 x + y ) - 2 ( 2 x - y )}{( 2 x + y ) ^{2}}

Expand

2 (2 x + y) - 2 (2 x - y) : 4 y

= \frac{4 y}{( 2 x + y ) ^{2}}
