So I'm trying to find A^-1 (inverse) matrix. The theorem I'm supposed to use for this is of a matrix using its Adjoint.

A^-1 = [1 / det(A)] * [adj(A)]

The matrix used is A =

2 0 0

8 1 0

-5 3 6

I expanded the matrix using cofactors and obtained

c11=6, c12=48, c13=29

c21=0, c22=12, c23=6

c31=0, c32=0, c33=2

so the matrix cofactor is

6 48 29

0 12 6

0 0 2

and the adjoint of A is

6 0 0

48 12 0

29 6 2

now what do I do? I'm stuck here.
