\frac{d}{d x} (\frac{( x - 7 )}{x + 7})

\frac{7}{x ( x + 7 ) ^{2}}

Solution steps

\frac{d}{d x} (\frac{( x - 7 )}{x + 7})

Apply the Quotient Rule:

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

= \frac{\frac{d}{d x} ( x - 7 ) ( x + 7 ) - \frac{d}{d x} ( x + 7 ) ( x - 7 )}{( x + 7 ) ^{2}}

\frac{d}{d x} (x - 7) = \frac{1}{2 x}

\frac{d}{d x} (x + 7) = \frac{1}{2 x}

= \frac{\frac{1}{2 x} ( x + 7 ) - \frac{1}{2 x} ( x - 7 )}{( x + 7 ) ^{2}}

Simplify

\frac{\frac{1}{2 x} ( x + 7 ) - \frac{1}{2 x} ( x - 7 )}{( x + 7 ) ^{2}} : \frac{7}{x ( x + 7 ) ^{2}}

= \frac{7}{x ( x + 7 ) ^{2}}

\int e^{2 x} sin (3 x) d x

\int_{1}^{12} \frac{1}{x - 9} d x

n = 1 \sum \infty \frac{1}{n + 4}

\frac{\partial}{\partial x} (x \cdot e^{x} + ln (x) y)

\int - 7 ln (x^{2} - 1) d x
