If A is a square matrix such that `|A| ne 0 and m, n (ne 0)` are scalars such that `A^(2)+mA+nI=0`, then `A^(-1)=`

If A is square matrix such that |A| ne 0 and A^2-A+2I=O " then " A^(-1) =?

If A is a 2 xx 2 matrix such that |A| ne 0 " and " |A| = 5, write the value of |4A|.

If A is a ntimesn matrix and |A|ne0 , then adj(adjA)=

If A is a square matrix of order 2, |A| ne 0 and |4A| = k |A|, then the value of k is :

If A is a square matrix of order less than 4 such that |A-A^(T)| ne 0 and B= adj. (A), then adj. (B^(2)A^(-1) B^(-1) A) is
