congrats Artes, I didn't know that this is possible to do. But I think in any case big knowledge is necessary for this

comment How to apply RootLocusPlot corectly
@Öskå I picked up the point just on the part of the question already asked. To take a look is it better for understanding because the problem is more complex that I thought.My previous question is large and consists of few parts. I didn't get any sign for further analysis.

@bill s I tried RootLocusPlot[a6 r^2-a1 a3 k^4 - a2 a4 (-k a5 + r)^2], {k, 0, 0.01000}] but it is not that diagram

how to be sure that there are only two roots. I know that all of them should be complex, but more then two. Thank you anyway.
