The maximum value of \(\left| z \right|\) when \(z\) satisfies the condition \(\left| z + \frac{2}{z}\right| = 2\) is

The answer is \(\sqrt{3} + 1\)

I M weak in formatting so hope u understand Minimum value of |z + 2/z| is ||z|-|2/z|| so equating it with 2 gives us quadratic of |z|--> |z|^2 -2|z| -2 = 0 Krishna Sharma · 2 years, 2 months ago
