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

Find x if det A = 0 where A = [(x+1,-3,4),(-5,x+2,2),(4,1,x-6)]

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

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 |[2,4],[5,1]|=|[2x,4],[6,x]| then x is

If f(x)=|[3,2,1],[6x^(2),2x^(3),x^(4)],[1,a,a^(2)]| ,then f''(a)= is

If f(x)=|[3x^2-x+3,6x-1,4],[6x^2-4x+5,12x-4,8],[3x^2+2x+5,6x+2,4]|, then the degree of the polynomial f(x) is

if f(x)=|[x-3,2x^2-18,3x^3-81],[x-5,2x^2-50,4x^3-500],[1,2,3]| then f(1)f(3)+f(3)f(5)+f(5)f(1) is equalto

if f(x)=|[x-3,2x^2-18,3x^3-81],[x-5,2x^2-50,4x^3-500],[1,2,3]| then f(1)f(3)+f(3)f(5)+f(5)f(1) 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
