integral of ln(3x^2)

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

x (ln (3) + 2 ln (x)) - 2 x + C

Solution steps

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

Apply Integration By Parts

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

\int 2 d x = 2 x

= x ln (3 x^{2}) - 2 x

Simplify

ln (3 x^{2}) : 2 ln (x) + ln (3)

= x (ln (3) + 2 ln (x)) - 2 x

Add a constant to the solution

= x (ln (3) + 2 ln (x)) - 2 x + C

What is the integral of ln(3x^2) ?
The integral of ln(3x^2) is x(ln(3)+2ln(x))-2x+C
