Saya mau tnya ttg matriks ( Di atas 5 dan -3,dibawah -2 & 1)+(di atas 0 & 1,d bwah -1 &5) =A( d atas -3 dan 2 ,d bwah -1 dan 2) maka matriks A adalah
dwi2
(d atas 5&-3,d bwh -2&1) + (d atas 0&1,d bwh -1&5) = A(d atas -3&2,d bwh -1&2) (d atas 5&-2,d bwh -3&6) = A (d atas -3&2,d bwh -1&2) A = (d atas 5&-2,d bwh -3&6) x (1/(-3).(2)-(-1).(2)) x (d atas 2&-2,d bwh 1&-3) A = (1/(-6)-(-2)) x (d atas (5).(2)+(-2).(1))&((5).(-2)+(-2).(-3)),d bwh ((-3).(2)+(6).(1))&((-3).(-2)+(6).(-3) A = (-1/4) x (d atas 8&-4,d bwh 0&-12) A= (d atas -2&1,d bwh 0&3)
(d atas 5&-2,d bwh -3&6) = A (d atas -3&2,d bwh -1&2)
A = (d atas 5&-2,d bwh -3&6) x (1/(-3).(2)-(-1).(2)) x (d atas 2&-2,d bwh 1&-3)
A = (1/(-6)-(-2)) x (d atas (5).(2)+(-2).(1))&((5).(-2)+(-2).(-3)),d bwh ((-3).(2)+(6).(1))&((-3).(-2)+(6).(-3)
A = (-1/4) x (d atas 8&-4,d bwh 0&-12)
A= (d atas -2&1,d bwh 0&3)
