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

Step 1

Integrate by parts using the formula $\int u d v = u v - \int v d u$ , where $u = \ln ({(x)}^{2})$ and $d v = 1$ .

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

Step 2

Step 2.1

Combine $x$ and $\frac{2}{x}$ .

$\ln (x^{2}) x - \int \frac{x \cdot 2}{x} d x$

Step 2.2

Move $2$ to the left of $x$ .

$\ln (x^{2}) x - \int \frac{2 \cdot x}{x} d x$

Step 2.3

Cancel the common factor of $x$ .

Step 2.3.1

Cancel the common factor.

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

Step 2.3.2

Divide $2$ by $1$ .

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

Step 3

Apply the constant rule.

$\ln (x^{2}) x - (2 x + C)$

Step 4

Rewrite $\ln (x^{2}) x - (2 x + C)$ as $\ln (x^{2}) x - 2 x + C$ .

$\ln (x^{2}) x - 2 x + C$
