Also wondering why we don't get a third vector by setting x=0. Could someone clarify this to me?

sir why didn't you make x =0 ? and get a 3 vector

Professor, why did we not substitute x=0 and find vector v3? The vector set would contain 3 vectors?

sir, why didnt u find the eigenvector when letting x=0 ??? shouldnt we have 3 eigenvector for the set of bases??

In my understand, we can create v3 = v1*3/4 - v2 = [0, 5*3/4, -5]
So that the v3 vector is dependent on v1 and v2 then it should not be a basis of matrix
Am i right?
