SUMMARY
The distance from the point (-2,3) to the center of the circle defined by the equation x² + 2x + y² - 2y - 3 = 0 is calculated using the distance formula. The center of the circle is confirmed to be at the coordinates (-1,1). The distance is computed as √((-1+2)² + (1-3)²), resulting in a definitive distance of √5. Additionally, it is confirmed that the point (-2,3) is not on the circle.
