If `[1, x, 2][[2,3,1],[0,4,2],[0,3,2]][[x],[1],[-1]]=0,` then the value of x is

If [[1,x,1]][[1,2,3],[0,5,1],[0,3,2]][[x],[1],[-2]]=0 , then the value of x is

If [[1,x,1]][[1,3,2],[0,5,1],[0,3,2]][[x],[1],[-2]]=0 , then x is

If x^2 - 3x +1=0, then the value of x +1/x is

IF " "[x,4,-1][[2,1,-1],[1,0,0],[2,2,4]][x,4,-1]^(TT) -0" then value of x:

If [(1,2,1)][(1,2,0),(2,0,1),(1,0,2)] [(0),(2),(x)] = 0 , then the value of x is

If [(1,x,1)][(1,3,2),(0,5,1),(0,3,2)][(x),(1),(-2)]=[0] then x is

The value of x so that [[1,x,1]][[1,3,2] , [0,5,1] , [0,3,2]][[1], [1], [x]]=0 is

If |[1,x,x^2] , [x,x^2,1] , [x^2,1,x]|=3 then find the value of |[x^3-1, 0, x-x^4] , [0,x-x^4, x^3-1] , [x-x^4, x^3-1, 0]|
