1. **State the problem:** Solve the equation $$\frac{x^2}{5} - x = \frac{1}{5}$$ for $x$.
2. **Rewrite the equation:** Multiply both sides by 5 to clear the denominators:
$$x^2 - 5x = 1$$
3. **Bring all terms to one side:**
$$x^2 - 5x - 1 = 0$$
4. **Use the quadratic formula:** For an equation $ax^2 + bx + c = 0$, the solutions are
$$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$
Here, $a=1$, $b=-5$, and $c=-1$.
5. **Calculate the discriminant:**
$$\Delta = b^2 - 4ac = (-5)^2 - 4(1)(-1) = 25 + 4 = 29$$
6. **Find the roots:**
$$x = \frac{-(-5) \pm \sqrt{29}}{2(1)} = \frac{5 \pm \sqrt{29}}{2}$$
7. **Final answer:**
$$x = \frac{5 + \sqrt{29}}{2}, \frac{5 - \sqrt{29}}{2}$$
These are the exact solutions in simplest form.
