For how many values of p, the circle `x^2+y^2+2x+4y-p=0` and the coordinate axes have exactly three common points?

The line y=x+asqrt2 touches the circle x^2+y^2=a^2 at P. The coordinate of P are

A tangent to the circle x^(2)+y^(2)=4 meets the coordinate axes at P and Q. The locus of midpoint of PQ is

If P(2,8) is an interior point of the circle x^2+y^2-2x+4y-p=0 , which neither touches nor intersects the axes, then set of value of p, is
