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

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

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

Solution steps

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

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

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

Apply Integration By Parts

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

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

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

Add a constant to the solution

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