1. **State the problem:** Simplify or analyze the quadratic expression $3x^2 - 4x + 1$.
2. **Recall the quadratic formula:** For any quadratic equation $ax^2 + bx + c = 0$, the solutions are given by
$$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$
where $a=3$, $b=-4$, and $c=1$.
3. **Calculate the discriminant:**
$$\Delta = b^2 - 4ac = (-4)^2 - 4 \times 3 \times 1 = 16 - 12 = 4$$
4. **Find the roots:**
$$x = \frac{-(-4) \pm \sqrt{4}}{2 \times 3} = \frac{4 \pm 2}{6}$$
5. **Evaluate each root:**
- For the plus sign:
$$x = \frac{4 + 2}{6} = \frac{6}{6} = 1$$
- For the minus sign:
$$x = \frac{4 - 2}{6} = \frac{2}{6} = \frac{1}{3}$$
6. **Final answer:** The roots of the quadratic $3x^2 - 4x + 1$ are
$$x = 1 \quad \text{and} \quad x = \frac{1}{3}$$
