Homework Statement



Determine the values of z \in \mathbb{C} for which |z+2| > 1 + |z-2| holds.

Homework Equations



Nothing complicated I can think of.

The Attempt at a Solution



For real values this holds for anything greater than 1/2. If I could figure out the boundaries of the area I'd be set, but the triangle inequality doesn't return anything nontrivial here. Tedious expansion into real and imaginary terms could be a solution, but there's probably a better way.

I've found out through wolfram alpha that the inequality holds for an area enclosed by two crossing lines. Not quite sure where to get the two lines from
 
There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
