Answer:
x2 + y2 + 4x - 7 = 0 2x2 + 2y2 + 3x + 5y - 9 = 0 x2 + y2 + y = 0 . ... the equation of the circle which cuts the following circles orthogonally.
Top answer
Let the circle required be x2 + y2 + 2gx + 2fy + c = 0 We know two circles intersect orthogonalif: 2g1g2 + 2f1f2 = c1 + c2 Hence, here : 2( - 2)(g) + 2(0) ... More. and please follow me and marks as me brilliant
