<prompt> Acha mathbfA anzepmatrix 1 5 1 3 endpmatrix. Pata nambari zote halisi x ili kwamba matrix mathbfA - x mathbf I haibadiliki. Ingiza suluhu zote, zikitenganishwa na koma.  <response>: Kwanza,mathbfA - x mathbfI anzapmatrix 1 5 1 3 mwishopmatrix - x anzapmatrix 1 0 0 1 mwisho pmatrix anzapmatrix 1 - x 5 1 3 - x mwishopmatrix.Hii haiwezi kugeuzwa wakati kibainishi chake ni sifuri, kwa hivyo 1 - x3 - x - 51 0. Hii hurahisisha hadi x2 - 4x - 2 0. Mizizi ni 2 sqrt6, 2 - sqrt6.
