Question

find the inverse of the matrix A= [234|431|124] with explain​

Answer 1

Firstly we solved Matrix A,

Then Finding minors

then Finding cofactors

Then doing the transpose of matrix of cofactor which is our adj |A| .

The Using the formula ,

${A}^{ - 1} = adj |A| \frac {1}{| A |}$

Inverse Of matrix

$the \: inverse \: of \: A \: is \: {A}^{ - 1} \: when \: \\ A \: \times {A}^{ - 1} = {A}^{ - 1} \times A = I \: (identity \: matrix)$
