Solution :
Let the equation of circle be \((x-3)^2 + (y-0)^2 + \lambda y\) = 0
As it passes through (1, -2)
\(\therefore\) \((1-3)^2 + (-2)^2 + \lambda (-2)\) = 0
\(\implies\) 4 + 4 โ 2\(\lambda\) = 0
\(\implies\) \(\lambda\) = 4
\(\therefore\) Equation of circle is \((x-3)^2 + y^2 + 4y\) = 0
By hit and trial method, we see that point (5, -2) satisfies the equation of circle.
