What is the locus of points that are exactly n times farther from P2 than from P1?

(P1 and P2 are two points in the x-y plane, and n is a positive real number)

the center of the circle is at c^2 / (c^2 - 1) and the radius is c/(c^2-1). Remember of course to scale up by the distance from P1 to P2.
