$y + \ln (| y |) + C_{3} = \ln (x^{2}) + \frac{- 1}{2} (2 x) - \frac{1}{2} (- \frac{2}{x}) + C_{7}$

Step 2.3.18.4.4.4

Rewrite the expression.

$y + \ln (| y |) + C_{3} = \ln (x^{2}) - x - \frac{1}{2} (- \frac{2}{x}) + C_{7}$

Step 2.3.18.4.5

Step 2.3.18.4.5.1

Move the leading negative in $- \frac{1}{2}$ into the numerator.

$y + \ln (| y |) + C_{3} = \ln (x^{2}) - x + \frac{- 1}{2} (- \frac{2}{x}) + C_{7}$

Step 2.3.18.4.5.2

Move the leading negative in $- \frac{2}{x}$ into the numerator.

$y + \ln (| y |) + C_{3} = \ln (x^{2}) - x + \frac{- 1}{2} \cdot \frac{- 2}{x} + C_{7}$

Step 2.3.18.4.5.3

Factor $2$ out of $- 2$ .

$y + \ln (| y |) + C_{3} = \ln (x^{2}) - x + \frac{- 1}{2} \cdot \frac{2 (- 1)}{x} + C_{7}$

Step 2.3.18.4.5.4

Cancel the common factor.

$y + \ln (| y |) + C_{3} = \ln (x^{2}) - x + \frac{- 1}{2} \cdot \frac{2 \cdot - 1}{x} + C_{7}$

Step 2.3.18.4.5.5

Rewrite the expression.

$y + \ln (| y |) + C_{3} = \ln (x^{2}) - x - \frac{- 1}{x} + C_{7}$

Step 2.3.18.5.2.1

Multiply $- 1$ by $- 1$ .

$y + \ln (| y |) + C_{3} = \ln (x^{2}) - x + 1 \frac{1}{x} + C_{7}$

Step 2.3.18.5.2.2

Multiply $\frac{1}{x}$ by $1$ .

$y + \ln (| y |) + C_{3} = \ln (x^{2}) - x + \frac{1}{x} + C_{7}$

Step 2.3.19

Reorder terms.

$y + \ln (| y |) + C_{3} = - x + \frac{1}{x} + \ln (x^{2}) + C_{7}$

Step 2.4

Group the constant of integration on the right side as $C$ .

$y + \ln (| y |) = - x + \frac{1}{x} + \ln (x^{2}) + C$
