1. **Stating the problem:**
We need to draw the parabola given by the equation $$y + 5 = x(6 - x)$$ after rewriting it in standard form.
2. **Rewrite the equation:**
Start with the given equation:
$$y + 5 = x(6 - x)$$
Expand the right side:
$$y + 5 = 6x - x^2$$
3. **Isolate y:**
Subtract 5 from both sides:
$$y = 6x - x^2 - 5$$
4. **Rewrite in standard quadratic form:**
Rearranged as:
$$y = -x^2 + 6x - 5$$
5. **Identify the parabola characteristics:**
- The coefficient of $$x^2$$ is $$-1$$, which means the parabola opens downward.
- The vertex form can be found by completing the square.
6. **Complete the square:**
$$y = -\left(x^2 - 6x\right) - 5$$
To complete the square inside the parentheses:
$$x^2 - 6x = (x^2 - 6x + 9) - 9 = (x - 3)^2 - 9$$
7. **Substitute back:**
$$y = -\left((x - 3)^2 - 9\right) - 5 = - (x - 3)^2 + 9 - 5 = - (x - 3)^2 + 4$$
8. **Interpretation:**
The vertex is at $$ (3, 4) $$.
The parabola opens downward because of the negative coefficient.
9. **Summary:**
The parabola equation in vertex form is:
$$y = - (x - 3)^2 + 4$$
This form is useful for graphing the parabola.
**Final answer:**
$$y = -x^2 + 6x - 5$$ or equivalently $$y = - (x - 3)^2 + 4$$
