Question 1206982
<pre>

Ikleyn should have simplified

 {{{sqrt(20)/2 - i*expr(sqrt(20)/2))}}}

 {{{sqrt(4*5)/2 - i*expr(sqrt(4*5)/2))}}}

 {{{2sqrt(5)/2 - i*expr(2sqrt(5)/2))}}}

 {{{cross(2)sqrt(5)/cross(2) - i*expr(cross(2)sqrt(5)/cross(2)))}}}

 {{{sqrt(5) - i*sqrt(5)}}}

And similarly, the other solution is

 {{{-sqrt(5) + i*sqrt(5)}}}
