Let C be the set of all complex numbers and C' be the set of all non-zero complex numbers. Let a relation R on C' be defined as z1 R z2↔(z1 - z2)/(z1 + z2) is real for. all z1, z2belonging to C'Show that R is an equivalence relation.

Answer» Let C be the set of all complex numbers and C' be the set of all non-zero complex numbers. Let a relation R on C' be defined as
z1 R z2↔(z1 - z2)/(z1 + z2) is real for.
all z1, z2belonging to C'
Show that R is an equivalence relation.
