**Steve**, Friday, April 25, 2014 at 5:53am|z-5-12i| is the distance of z from 5+12i

|z-5+12i| is the distance of z from 5-12i

As we know, the locus of a point whose distances from two other points add to a constant, is an ellipse.

The equation of the ellipse should be no problem, since you know the foci and the sum of the distances.
