Hi everyone, would anyone be willing to help me with a sage exercise related to the base of a radical of a bilinear form? Thank you. 

soon I attach the track

Ask sagemath has a similar question:

https://ask.sagemath.org/question/38132/quadratic-form/

Hope that helps.

Just FYI, typically this email list doesn't answer homework questions. However, if you have

sagemath code that you think should solve the problem but doesn't, please post your code

and maybe someone can help with that part of it.

I used google and found that Gap (which Sagemath includes) does something this:

https://www.gap-system.org/Manuals/pkg/forms/doc/chap4_mj.html

See the example for RadicalOfForm( f ) near the bottom of that webpage.

However, I'm not sure how you'd do that in SageMath itself, so this doesn't quite answer

your question. The webpage for the SageMath-Gap interface is here:

https://doc.sagemath.org/html/en/reference/interfaces/sage/interfaces/gap.html

Hope that helps.
