  1. A \(x^2+y^2-3 x+6 y+15=0\)
  2. B \(x^2+y^2-6 x+4 y+10=0\)
  3. C \(x^2+y^2-9 x+2 y+20=0\)
  4. D \(x^2+y^2-9 x-2 y+20=0\)
Verified Solution

Answer & Solution

Correct Answer

(D) \(x^2+y^2-9 x-2 y+20=0\)

Step-by-step Solution

Detailed explanation

Equation of given circles \[ \begin{aligned} & S_1=x^2+y^2-3 x+y-10=0 \\ & S_2=x^2+y^2-x+2 y-20=0 \end{aligned} \] \(\because\) Equation of family of circles passes through intersection of circles \(S_1\) and \(S_2\) is…
