derivative of

\frac{x - 5}{x + 5}

\frac{5}{x ( x + 5 ) ^{2}}

Solution steps

\frac{d}{d x} (\frac{x - 5}{x + 5})

Apply the Quotient Rule:

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

= \frac{\frac{d}{d x} ( x - 5 ) ( x + 5 ) - \frac{d}{d x} ( x + 5 ) ( x - 5 )}{( x + 5 ) ^{2}}

\frac{d}{d x} (x - 5) = \frac{1}{2 x}

\frac{d}{d x} (x + 5) = \frac{1}{2 x}

= \frac{\frac{1}{2 x} ( x + 5 ) - \frac{1}{2 x} ( x - 5 )}{( x + 5 ) ^{2}}

Simplify

\frac{\frac{1}{2 x} ( x + 5 ) - \frac{1}{2 x} ( x - 5 )}{( x + 5 ) ^{2}} : \frac{5}{x ( x + 5 ) ^{2}}

= \frac{5}{x ( x + 5 ) ^{2}}

l a pl a ce t r an s f or m f (t) = (1 + e^{2 t})^{2}

\frac{d}{d x} (4 - 6 x)

\frac{d}{d x} (x - 9)

\frac{d x}{d t} + t x^{3} + \frac{x}{t} = 0

\int \frac{1}{3 3 x ^{5}} d x
