Show that the set all points such that the difference of their distances from `(4,0)a n d(-4,0)` is always equal to 2 represents a hyperbola.

Explanation

It is given that the difference of the distance between the point (4,0) and (−4,0) is 2

Hence


Distance between points is



`sqrt((x−4)^2+(y−0)^2
​−(x+4)^2+(y−0)^2`
