1. **State the problem:** Solve the quadratic equation $$8x^2 - 19x + 6 = 0$$ for $x$.
2. **Formula used:** To solve a quadratic equation of the form $$ax^2 + bx + c = 0$$, use the quadratic formula:
$$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$
where $a=8$, $b=-19$, and $c=6$.
3. **Calculate the discriminant:**
$$\Delta = b^2 - 4ac = (-19)^2 - 4 \times 8 \times 6 = 361 - 192 = 169$$
Since $\Delta > 0$, there are two distinct real roots.
4. **Find the roots:**
$$x = \frac{-(-19) \pm \sqrt{169}}{2 \times 8} = \frac{19 \pm 13}{16}$$
5. **Evaluate each root:**
- For the plus sign:
$$x = \frac{19 + 13}{16} = \frac{32}{16} = 2$$
- For the minus sign:
$$x = \frac{19 - 13}{16} = \frac{6}{16} = \frac{3}{8}$$
6. **Final answer:**
$$x = 2 \quad \text{or} \quad x = \frac{3}{8}$$
These correspond to option (a).
