\frac{d}{d x} (\frac{( x ^{2} - 2 e ^{x} )}{x + 3 e ^{x}})

\frac{x ^{2} - 3 e ^{x} x ^{2} + 4 e ^{x} x + 2 e ^{x}}{( x + 3 e ^{x} ) ^{2}}

Solution steps

\frac{d}{d x} (\frac{( x ^{2} - 2 e ^{x} )}{x + 3 e ^{x}})

Apply the Quotient Rule:

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

= \frac{\frac{d}{d x} ( x ^{2} - 2 e ^{x} ) ( x + 3 e ^{x} ) - \frac{d}{d x} ( x + 3 e ^{x} ) ( x ^{2} - 2 e ^{x} )}{( x + 3 e ^{x} ) ^{2}}

\frac{d}{d x} (x^{2} - 2 e^{x}) = 2 x - 2 e^{x}

\frac{d}{d x} (x + 3 e^{x}) = 1 + 3 e^{x}

= \frac{( 2 x - 2 e ^{x} ) ( x + 3 e ^{x} ) - ( 1 + 3 e ^{x} ) ( x ^{2} - 2 e ^{x} )}{( x + 3 e ^{x} ) ^{2}}

Expand

(2 x - 2 e^{x}) (x + 3 e^{x}) - (1 + 3 e^{x}) (x^{2} - 2 e^{x}) : x^{2} - 3 e^{x} x^{2} + 4 e^{x} x + 2 e^{x}

= \frac{x ^{2} - 3 e ^{x} x ^{2} + 4 e ^{x} x + 2 e ^{x}}{( x + 3 e ^{x} ) ^{2}}

\int \frac{1}{x 3 x} d x

\frac{d}{d x} (2 ln (x^{2} + y^{2}))

t y^{^{'}} = (1 - y^{2})^{\frac{1}{2}}

\int \frac{e ^{2 x}}{x ^{2}} d x

\frac{1}{x - 1}, 18
