<prompt> Tafuta matrix mathbfM ambayo huongeza safu wima ya kwanza maradufu. Kwa maneno mengine,mathbfM anzapmatrix a b c d endpmatrix anzapmatrix 2a b 2c d endpmatrix.Kama hakuna vile matrix mathbfM ipo, kisha ingiza sifuri matrix.  <response>: Acha mathbfM anzepmatrix p q r s endpmatrix. KishamathbfM anzapmatrix a b c d mwishopmatrix anzapmatrix p q r s mwishopmatrix anzapmatrix a b c d endpmatrix anzapmatrix pa qc pb qd ra sc rb sd endpmatrix.Tunataka hii iwe sawa na beginpmatrix 2a b 2c d endpmatrix. Hakuna viambajengo p,q,r,s ambavyo vitafanya kazi hii, kwa hivyo jibu ni sifuri tumbo anzapmatrix 0 0 0 0 endpmatrix.
