derivative of

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

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

Solution steps

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

Apply the chain rule:

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

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

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

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

Simplify

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

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