1. **State the problem:** Solve the complex equation $$p(z) = z^2 - 3z^2 + z + 5$$ for $z$.
2. **Simplify the polynomial:** Combine like terms:
$$p(z) = z^2 - 3z^2 + z + 5 = -2z^2 + z + 5$$
3. **Set the polynomial equal to zero to find roots:**
$$-2z^2 + z + 5 = 0$$
4. **Rewrite the equation:**
$$-2z^2 + z + 5 = 0 \implies 2z^2 - z - 5 = 0$$
5. **Use the quadratic formula:** For $az^2 + bz + c = 0$, roots are
$$z = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$
Here, $a=2$, $b=-1$, $c=-5$.
6. **Calculate the discriminant:**
$$\Delta = b^2 - 4ac = (-1)^2 - 4(2)(-5) = 1 + 40 = 41$$
7. **Find the roots:**
$$z = \frac{-(-1) \pm \sqrt{41}}{2 \times 2} = \frac{1 \pm \sqrt{41}}{4}$$
8. **Final answer:** The solutions to the equation are
$$z = \frac{1 + \sqrt{41}}{4} \quad \text{and} \quad z = \frac{1 - \sqrt{41}}{4}$$
