" If the trace of the matrix: "A=[[-1,0,2,5],[3,x^(2)-2,4,1],[-1,-2,x-3,1],[2,0,4,x^(2)-6]]" is "0" then "x" is equal to "

If the trace of the matrix A= [{:( x-1 ,0,2,5),( 3, x^(2) - 2 ,4,1),( -1,-2,x-3,1),(2,0,4,x^(2)-6) :}] is 0 then x is equal to

If the trace of the matrix A=({:(x-5,0,2,4),(3,x^(2)-10,6,1),(-2,3,x-7,1),(1,2,0,-2):}) assumes the value zero, then the value of x equals to

If |(1,-3,4),(-5,x+2,2),(4,1,x-6)|=0 then x equals

if [{:(3,2),(7,5):}]A{:[(-1,1),(-2,1):}]={:[(2,-1),(0,4):}] then trace of A is equal to

Solve for x: |[x^2+1,0,3x+2],[x,2,1],[4x,-1,0]|=0

If [(2,1),(7,4)]A[(-3,2),(5,-3)]=[(1,0),(0,1)] then matrix A equals

Find matrix X if X + [[2,5],[3,-1]], =[[3,4], [2,0]]

If |[2x,-1],[4,2]|=|[3,0],[2,1]| then x is
