show that the matrix A=[(2,-2,-4),(-1,3,4),(1,-2,-3)] is idempotent.

show that the matrix A=[(2,-2,-4),(-1,3,4),(1,-2,-3)] is idempotent.

show that the matrix A=[(2,-2,-4),(-1,3,4),(1,-2,-3)] is idempotent.

show that the matrix A=[(2,-2,-4),(-1,3,4),(1,-2,-3)] is idempotent.

Express the matrix [[2,-2,-4],[-1,3,4],[1,-2,-3]] as the sum of a symmetric and a skew symmetric matrices.

If A=[[2,-2,-4],[-1,3,4],[1,-2,-3]] then A is 1) an idempotent matrix 2) nilpotent matrix 3) involutary 4) orthogonal matrix
