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

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

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

Solution steps

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

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

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

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

Simplify

\frac{1 \cdot ( x ^{2} - y ) - 2 x ( x + 2 y )}{( x ^{2} - y ) ^{2}} : \frac{- x ^{2} - 4 x y - y}{( x ^{2} - y ) ^{2}}

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

z \to 1 + i lim (z^{2} + i)

\int (3 x - 5)^{4} d x

\int \frac{1 + x}{x ^{2}} d x

f (x) = - x^{2} + 3 x + 2

f (x) = 5 x^{2} + 3 x + 8
