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

\frac{- 3 x ^{2} - 4 x + 3}{( x ^{2} + 1 ) ^{2}}

Solution steps

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

Apply the Quotient Rule:

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

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

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

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

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

Expand

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

= \frac{- 3 x ^{2} - 4 x + 3}{( x ^{2} + 1 ) ^{2}}

g (x) = e^{x^{5}}, (- 1, \frac{1}{e})

\frac{\partial}{\partial x} (2 ln (x))

t^{2} e^{2 t}
