Can anyone help me solve this modulus problem
(|z+2|+|z-4|)=10
I thought about squaring both sides but that gets very fiddly.

Hey!! Does z represent a complex number? Should u find the locus represented by this eqn?

if z is complex this equation has infinite solution which lie on an ellipse in an Argand diagram
if z is real there are unique answers
solve by a graph or by considring the critical values or the mods

Hmm, well yes, I am looking for values of -4,0 and 6,0 for the major axis of the ellipse.
How would I find the minor/major axis here?
