1. **State the problem:** Solve the quadratic equation $$6w^2 - 26w + 5 = w^2$$ for $w$ using the quadratic formula.
2. **Rewrite the equation:** Move all terms to one side to set the equation to zero:
$$6w^2 - 26w + 5 - w^2 = 0$$
Simplify:
$$5w^2 - 26w + 5 = 0$$
3. **Identify coefficients:** For the quadratic equation $$aw^2 + bw + c = 0$$, here:
$$a = 5, \quad b = -26, \quad c = 5$$
4. **Quadratic formula:**
$$w = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$
5. **Calculate the discriminant:**
$$\Delta = b^2 - 4ac = (-26)^2 - 4 \times 5 \times 5 = 676 - 100 = 576$$
6. **Square root of discriminant:**
$$\sqrt{576} = 24$$
7. **Apply the quadratic formula:**
$$w = \frac{-(-26) \pm 24}{2 \times 5} = \frac{26 \pm 24}{10}$$
8. **Find the two solutions:**
- For the plus sign:
$$w = \frac{26 + 24}{10} = \frac{50}{10} = 5$$
- For the minus sign:
$$w = \frac{26 - 24}{10} = \frac{2}{10} = \frac{1}{5}$$
9. **Final answer:**
$$w = 5 \quad \text{or} \quad w = \frac{1}{5}$$
