`A^(3)-2A^(2)-A+2I=0` if `A=`

If A is a square matrix of order 3 and I is an ldentity matrix of order 3 such that A^(3) - 2A^(2) - A + 2I =0, then A is equal to

If A = [(1,0,2),(0,2,1),(2,0,3)] , prove that A^(3) -6A^(2) + 7A + 2I = 0 .

If a matrix A is such that 3A^(3)+2A^(2)+5A+I=0, then A^(-1) is equal to

If a matrix A is such that 3A^(3)+2A^(2)+5A+I=0 , then its inverse is

If A^(2)-3A+2I=0 , then A =

If A^(2)-3A+2I=0 then

For the matrix A=[(1,1,0),(1,2,1),(2,1,0)] which of the following is correct? (A) A^3+3A^2-I=0 (B) A^3-3A^2-I=0 (C) A^3+2A^2-I=0 (D) A^3-A^2+I=0

For the matrix A=[(1,1,0),(1,2,1),(2,1,0)] which of the following is correct? (A) A^3+3A^2-I=0 (B) A^3-3A^2-I=0 (C) A^3+2A^2-I=0 (D) A^3-+A^2-+I=0
