Inverting a 3x3 matrix using determinants Part 2: Adjugate matrix

Find a (Adj A) for the Matrix a = ⎡ ⎢ ⎣ 1 − 2 3 0 2 − 1 − 4 5 2 ⎤ ⎥ ⎦ . - Mathematics | Shaalaa.com

SOLVED: Compute the adjugate of the given matrix, and then use the Inverse Formula to give the inverse of the matrixThe adjugate of the given matrix is adj A = (Type an integer or simplified fraction for each matrix element ) The inverse of the given matrix is A -1 = (Type an integer or simplified fraction for each matrix element )

In Exercises 11–16, compute the adjugate of the given matrix, and then use Theorem 8 to give the inverse of the matrix. [ 1 -1 2 0 2 1 2 0 4] | Numerade
