` |[x,-6,-1],[2,-3x,x-3],[-3,2x,x+2]|`=0

Show that x = 2 is a root of the equation |[x, -6, -1], [2, -3x, x-3], [-3, 2x, 2+x]|=0

Solve for x,det[[x,-6,-12,-3x,x-3-3,2x,x+2]]=0

x, -6, -12, -3x, x-3-3,2x, x + 2] | = 0

Solve for x: /_\=|[2x,3,1],[4,6,x],[3x,1,1]| = 0

If phi(x)= |[1,2x,3x^2], [x,x^2,x^4], [0,2,6x]| then phi'(1) =

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

Find the value of x, if |[(3+x), 5, 2],[1, (7+x), 6], [2, 5, (3+x)]| = 0

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 A=[[1/3,2],[0,2x-3]] , B=[[3,6],[0,-1]] and AB=I ,then x=
