derivative of (x+3/(x+1))

Solution

\frac{d}{d x} (\frac{x + 3}{x + 1})

Solution

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

Solution steps

\frac{d}{d x} (\frac{x + 3}{x + 1})

Apply the Quotient Rule:

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

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

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

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

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

Simplify

\frac{1 \cdot ( x + 1 ) - 1 \cdot ( x + 3 )}{( x + 1 ) ^{2}} : - \frac{2}{( x + 1 ) ^{2}}

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