Find the equation of the circle passing through (−1,2)(-1, 2)(−1,2), (2,1)(2, 1)(2,1), and (1,−2)(1, -2)(1,−2).
x2+y2−2x−2y−7=0x^2 + y^2 - 2x - 2y - 7 = 0x2+y2−2x−2y−7=0
x2+y2−2x+2y−7=0x^2 + y^2 - 2x + 2y - 7 = 0x2+y2−2x+2y−7=0
x2+y2+2x+2y−7=0x^2 + y^2 + 2x + 2y - 7 = 0x2+y2+2x+2y−7=0
x2+y2+2x−2y−7=0x^2 + y^2 + 2x - 2y - 7 = 0x2+y2+2x−2y−7=0
