Find the rank of matrix : A= [[1,2,-2,3],[2,5,-4,6],[-1,-3,2,-2],[2,4,-1,6]]

Find A^2-5A+6I , if A=[[2,0,1],[2,1,3],[1,-1,0]]

Find A^2-5A+6 if A=[[2,0,1],[2,1,3],[1,-1,0]]

Find A^2-5A+6I if A=[[2,0,1],[2,1,3],[1,-1,0]]

Without expanding prove that: |[12, 2, 4, -5, 1],[-8, 1, -5, 2, -1],[6, 4, a ,-3, 2],[-10, 2, 1 ,3 ,4],[-2, 4, 6 ,8, -5]|=|[12, -4, -8, 10, -2],[4, 1, -5, 2, -1],[-3, 4, a, -3, 2],[5, 2, 1, 3, 4],[1, 4, 6, 8, -5]| .

If A = [[2,0,1],[2,1,3],[1,-1,0]] then find A^2-5A+6I .

If A=[[2,0,1],[2,1,3],[1,-1,0]] , then find value of A^(2)-5A+6I

If A= [[2,0,1],[2,1,3],[1,-1,0]] , find A^2-5A+6I=O
