integral of (ln(3x))/(x^2)

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

- \frac{ln ( 3 x )}{x} - \frac{1}{x} + C

Solution steps

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

Apply Integration By Parts

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

\int - \frac{1}{x ^{2}} d x = \frac{1}{x}

= - \frac{ln ( 3 x )}{x} - \frac{1}{x}

Add a constant to the solution

= - \frac{ln ( 3 x )}{x} - \frac{1}{x} + C
