1. **State the problem:** Find the center and radius of the circle given by the equation $$x^2 + y^2 + 2x - 6y + 5 = 0$$.
2. **Rewrite the equation:** Group $x$ and $y$ terms:
$$x^2 + 2x + y^2 - 6y = -5$$
3. **Complete the square:**
For $x$ terms: $$x^2 + 2x = (x+1)^2 - 1^2 = (x+1)^2 - 1$$
For $y$ terms: $$y^2 - 6y = (y-3)^2 - 3^2 = (y-3)^2 - 9$$
4. **Substitute back:**
$$(x+1)^2 - 1 + (y-3)^2 - 9 = -5$$
5. **Simplify:**
$$(x+1)^2 + (y-3)^2 - 10 = -5$$
$$(x+1)^2 + (y-3)^2 = 5$$
6. **Identify center and radius:**
Center: $$(-1, 3)$$
Radius: $$\sqrt{5}$$
**Final answer:** The circle has center at $(-1,3)$ and radius $\sqrt{5}$.
