1. **State the problem:** We need to rewrite the sum of two algebraic fractions with different denominators by finding a common denominator and expressing both fractions with that denominator.
2. **Given expressions:**
$$\frac{(2x - 3)(x + 1)}{x(x - 1)(x - 1)} + \frac{(3x + 2)(x - 1)}{x(x - 1)(x + 1)}$$
3. **Identify the denominators:**
- First denominator: $x(x - 1)(x - 1) = x(x - 1)^2$
- Second denominator: $x(x - 1)(x + 1)$
4. **Find the least common denominator (LCD):**
The LCD must include each factor the greatest number of times it appears in any denominator.
- $x$ appears once in both.
- $(x - 1)$ appears twice in the first denominator and once in the second, so take $(x - 1)^2$.
- $(x + 1)$ appears once in the second denominator.
Therefore, the LCD is:
$$x(x - 1)^2(x + 1)$$
5. **Rewrite each fraction with the LCD:**
- First fraction already has denominator $x(x - 1)^2$, so multiply numerator and denominator by $(x + 1)$:
$$\frac{(2x - 3)(x + 1) \times (x + 1)}{x(x - 1)^2 (x + 1)} = \frac{(2x - 3)(x + 1)^2}{x(x - 1)^2 (x + 1)}$$
- Second fraction has denominator $x(x - 1)(x + 1)$, missing one $(x - 1)$ to match $(x - 1)^2$, so multiply numerator and denominator by $(x - 1)$:
$$\frac{(3x + 2)(x - 1) \times (x - 1)}{x(x - 1)(x + 1)(x - 1)} = \frac{(3x + 2)(x - 1)^2}{x(x - 1)^2 (x + 1)}$$
6. **Final rewritten expression:**
$$\frac{(2x - 3)(x + 1)^2}{x(x - 1)^2 (x + 1)} + \frac{(3x + 2)(x - 1)^2}{x(x - 1)^2 (x + 1)}$$
This matches the option:
$$\frac{(2x - 3)(x + 1)}{x(x - 1)(x + 1)} + \frac{(3x + 2)(x - 1)}{x(x + 1)(x - 1)}$$
which is the second option in the list.
**Answer:** The correct rewritten expression with the common denominator is:
$$\frac{(2x - 3)(x + 1)}{x(x - 1)(x + 1)} + \frac{(3x + 2)(x - 1)}{x(x + 1)(x - 1)}$$
