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

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

\frac{3 y}{( x + 2 y ) ^{2}}

Solution steps

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

\frac{\partial}{\partial x} (x - y) = 1

\frac{\partial}{\partial x} (x + 2 y) = 1

= \frac{1 \cdot ( x + 2 y ) - 1 \cdot ( x - y )}{( x + 2 y ) ^{2}}

Simplify

\frac{1 \cdot ( x + 2 y ) - 1 \cdot ( x - y )}{( x + 2 y ) ^{2}} : \frac{3 y}{( x + 2 y ) ^{2}}

= \frac{3 y}{( x + 2 y ) ^{2}}
