1. **State the problem:** Find the solutions of the equation $$2 - x^2 = -x$$ by graphing.
2. **Rewrite the equation:** To find the solutions, we want to find the values of $x$ where the parabola $$y = 2 - x^2$$ intersects the line $$y = -x$$.
3. **Set the equations equal:** Since both equal $y$, set them equal to each other:
$$2 - x^2 = -x$$
4. **Bring all terms to one side:**
$$2 - x^2 + x = 0$$
5. **Rewrite in standard quadratic form:**
$$-x^2 + x + 2 = 0$$
Multiply both sides by $-1$ to simplify:
$$\cancel{-}x^2 + \cancel{x} + \cancel{2} = \cancel{0} \implies x^2 - x - 2 = 0$$
6. **Factor the quadratic:**
$$x^2 - x - 2 = (x - 2)(x + 1) = 0$$
7. **Solve for $x$:**
Set each factor equal to zero:
$$x - 2 = 0 \implies x = 2$$
$$x + 1 = 0 \implies x = -1$$
8. **Interpretation:** The solutions to the equation are $$x = 2$$ and $$x = -1$$, which correspond to the points where the parabola and the line intersect on the graph.
**Final answer:**
$$x = 2 \text{ or } x = -1$$
