Explanation:

Review the standard and expanded forms of circle equations, and solve problems concerning them. ... Practice set 3: Using the expanded equation of circles ... y+105x2+y2+18x+14y(x2+18x)+(y2+14y)(x2+18x+81)+(y2+14y+49)(x+9)2+(y+7)2(x ... I could move the centre, but I'm lost as to how the radius should be adjusted.
