hello everyone,

i'm using prime 2.0

i want to exclude 2 of my 3 solutions which are non-real ...

I'm not really familiar with the Keywords and Modifiers,so i tried the "assume,var=real

which made everything only worse.....

i have searched a lot on google and elsewhere but couldnt find a solution for that problem....

maybe someone here can help...

thx in advance
