`|[x+1,2],[4,x-1]|=0`.The value of `x`

If |[x,1],[1,x]|=|[2,0],[8,4]| then value of x 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]|

If |(x,2,3),(2,3,x),(3,x,2)|=|(1,x,4),(x,4,1),(4,1,x)|=|(0,5,x),(5,x,0),(x,0,5)|=0, then the value of x equals (x in R):

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

If |{:(2,3,2),(x,x,x),(4,9,1):}|+3=0 then the value of x is

If (A -2I)(A-3I)=0 , when A=[{:(4,2),(-1,x):}] and I=[{:(1,0),(0,1):}] , find the value of x

If x^2+2a x+a<0AAx in [1,2], the find the values of a .

If [[(x+3y),y],[7-x,4]]=[(4,-1),(0,1)], find the values of x and y.
