integral of x^{-3}ln(-5x)

\int x^{- 3} ln (- 5 x) d x

- \frac{ln ( - 5 x )}{2 x ^{2}} - \frac{1}{4 x ^{2}} + C

Solution steps

\int x^{- 3} ln (- 5 x) d x

Apply Integration By Parts

= - \frac{ln ( - 5 x )}{2 x ^{2}} - \int - \frac{1}{2 x ^{3}} d x

\int - \frac{1}{2 x ^{3}} d x = \frac{1}{4 x ^{2}}

= - \frac{ln ( - 5 x )}{2 x ^{2}} - \frac{1}{4 x ^{2}}

Add a constant to the solution

= - \frac{ln ( - 5 x )}{2 x ^{2}} - \frac{1}{4 x ^{2}} + C
