# The circle passing through (1,-2) and touching the axis of x at (3, 0) also passes through the point
## 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 – 2$$\lambda$$ = 0
