derivative of x/(x+19)

Solution

\frac{d}{d x} (\frac{x}{x + 19})

Solution

\frac{19}{( x + 19 ) ^{2}}

Solution steps

\frac{d}{d x} (\frac{x}{x + 19})

Apply the Quotient Rule:

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

= \frac{\frac{d x}{d x} ( x + 19 ) - \frac{d}{d x} ( x + 19 ) x}{( x + 19 ) ^{2}}

\frac{d x}{d x} = 1

\frac{d}{d x} (x + 19) = 1

= \frac{1 \cdot ( x + 19 ) - 1 \cdot x}{( x + 19 ) ^{2}}

1 \cdot (x + 19) - 1 \cdot x = 19

= \frac{19}{( x + 19 ) ^{2}}
