integral of (ln(12x)-ln(4x))

\int (ln (12 x) - ln (4 x)) d x

x ln (12 x) - x ln (4 x) + C

Solution steps

\int ln (12 x) - ln (4 x) d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int ln (12 x) d x - \int ln (4 x) d x

\int ln (12 x) d x = x ln (12 x) - x

\int ln (4 x) d x = x ln (4 x) - x

= x ln (12 x) - x - (x ln (4 x) - x)

Simplify

= x ln (12 x) - x ln (4 x)

Add a constant to the solution

= x ln (12 x) - x ln (4 x) + C
