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

= 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

\int sin^{4} (b)

12 x e^{x}

\int \frac{x ^{2} - 7}{x ^{8}} d x

x \to 0 + lim (x^{2} ln (x^{2}))

\int (4 x - x^{2})^{2} d x
