Invers dari matriks b={3 -1
2. 2 adalah

Penjelasan dengan langkah-langkah:

[tex] = \frac{1}{ad - bc} \binom{d\: \: -b}{-c \: \: a} [/tex]

[tex] = \frac{1}{3.2 - ( - 1).2} \binom{2 \: \: 1}{ - 2 \: \: 3} [/tex]

[tex] = \frac{1}{8} \binom{2 \: \: 1}{ - 2 \: \: 3} [/tex]

[tex] = \binom{ \frac{2}{8} \: \: \frac{1}{8} }{ - \frac{2}{8} \: \: \frac{3}{8} } [/tex]

[tex] = \binom{ \frac{1}{4} \: \: \frac{1}{8} }{ - \frac{1}{4} \: \: \frac{3}{8} } [/tex]
