|[1,4,20],[1,-2,5],[1,2x,5x^(2)]|=0

Solve the following : [[1,4,20],[1,-2,5],[1,2x,5x^2]] =0

Let Delta=|(1,-4,20),(1,-2,5),(1,2,5x^(2))| Solution set of Delta=0 is

" 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 |[x^(3)+1,2x,1],[0,5+x,-3],[x-1,x^(2),2]|+|[3,2,1],[-1,5,-2],[0,4,6]|= ax^(5)+bx^(4)+cx^(3)+dx^(2)+ex+f is true for all x in R, then the value of f is

If A=[(x-1,0,2,5),(3,x^(2)-2,4,1),(-1,-2,x-3,1),(2,0,4,x^(2)-6)] and if Tr (A) = 0, then x is equal to

If x!=0 and |(1,x,2x),(1,3x,5x),(1,3,4)|=0 then x=

If X= [(2,3,0),(1,-1,5)] ,Y= [(-1,-2,3),(-1,0,2)] ,Z= [(0,4,-1),(5,6,-5)] find 3X+4Y-Z

Find x, if [x-5-1][[1, 0 ,2 ],[0,2, 1 ],[2 ,0 ,3]][[x],[4] ,[1]]=O .
