z

is a complex number in the Argand plane, then the equation

{\left| {z - 2} \right|^2} + {\left| {z + 2} \right|^2} = 8

represents

View answer and explanation

Correct option: D

A circle

The correct answer is D (A circle) because the simplified equation

{\left| {z - 2} \right|^2} + {\left| {z + 2} \right|^2} = 8

results in the equation of a circle.
