Limit Zero 354040
1. **State the problem:** Find the limit $$\lim_{x \to 0} \frac{x^3 - 3x^2 + x}{x^3 - 2x}$$.
2. **Recall the limit rules:** When direct substitution results in an indeterminate form like $$\frac{0}{0}$$, we try to simplify the expression by factoring or algebraic manipulation.
3. **Substitute $x=0$ directly:**
$$\frac{0^3 - 3\cdot0^2 + 0}{0^3 - 2\cdot0} = \frac{0}{0}$$ which is indeterminate.
4. **Factor numerator and denominator:**
- Numerator: $$x^3 - 3x^2 + x = x(x^2 - 3x + 1)$$
- Denominator: $$x^3 - 2x = x(x^2 - 2)$$
5. **Rewrite the limit:**
$$\lim_{x \to 0} \frac{x(x^2 - 3x + 1)}{x(x^2 - 2)}$$
6. **Cancel common factor $x$ (valid since $x \to 0$, $x \neq 0$):**
$$\lim_{x \to 0} \frac{x^2 - 3x + 1}{x^2 - 2}$$
7. **Substitute $x=0$ now:**
$$\frac{0^2 - 3\cdot0 + 1}{0^2 - 2} = \frac{1}{-2} = -\frac{1}{2}$$
**Final answer:** $$\boxed{-\frac{1}{2}}$$
