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

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

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

Solution steps

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

Treat

y

as a constant

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

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

Apply exponent rule:

\frac{1}{a} = a^{- 1}

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

Apply the chain rule:

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

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

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

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

Simplify

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

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