1. **State the problem:** Solve the equation $$\frac{3}{x+1} - \frac{2}{x^2-1} = \frac{1}{x^2 - x}$$ for $x$.
2. **Identify the denominators and factor where possible:**
- $x+1$ is linear.
- $x^2 - 1 = (x+1)(x-1)$ (difference of squares).
- $x^2 - x = x(x-1)$.
3. **Find the least common denominator (LCD):**
$$\text{LCD} = x(x+1)(x-1)$$
4. **Multiply both sides of the equation by the LCD to clear denominators:**
$$3 \cdot x(x-1) - 2 \cdot x = 1 \cdot (x+1)$$
5. **Write the equation after clearing denominators:**
$$3x(x-1) - 2x = x + 1$$
6. **Expand and simplify:**
$$3x^2 - 3x - 2x = x + 1$$
7. **Bring all terms to one side:**
$$3x^2 - 3x - 2x - x - 1 = 0$$
8. **Combine like terms:**
$$3x^2 - 6x - 1 = 0$$
9. **Solve the quadratic equation:**
Use the quadratic formula:
$$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$
where $a=3$, $b=-6$, $c=-1$.
10. **Calculate the discriminant:**
$$\Delta = (-6)^2 - 4 \cdot 3 \cdot (-1) = 36 + 12 = 48$$
11. **Find the roots:**
$$x = \frac{6 \pm \sqrt{48}}{6} = \frac{6 \pm 4\sqrt{3}}{6} = 1 \pm \frac{2\sqrt{3}}{3}$$
12. **Final answers:**
$$x_1 = 1 + \frac{2\sqrt{3}}{3}$$
$$x_2 = 1 - \frac{2\sqrt{3}}{3}$$
**Note:** Check for restrictions where denominators are zero: $x \neq -1$, $x \neq 0$, $x \neq 1$.
Both solutions do not violate these restrictions.
