The value of x for which the metrix product `{:[(2,0,7),(0,1,0),(1,-2,1)][(-x,14x,7x),(0,1,0),(x,-4x,-2x)]:}`equal an identity matrix, is

Find the value of x for which the matrix product [(2, 0, 7),( 0, 1, 0),( 1,-2, 1)][(-x, 14 x,7x),(0, 1, 0),(x,-4x,-2x)] equal to an identity matrix.

If A=[(x,1),(1,0)] and A^(2) is the identity matrix, then x is equal to

Find the matrix X for which: [(3, 2), (7, 5)]X[(-1, 1),(-2, 1)]=[(2,-1),( 0, 4)] .

The sum of the values of x so that the matrix ([2,2,1],[1,3,1],[1,2,2])-x([1,0,0],[0,1,0],[0,0,1]) is singular,is

What are the values of x that satisfy equation |(x,0,2),(2x,2,1),(1,1,1)|+|(3x,0,2),(x^(2),2,1),(0,1,1)| = 0 ?

If A=[(2x,0),(x,x)] and A^(-1)=[(1,0),(-1,2)] then x equals to

The value of 'x', when the matrix : A=[(0,1,-2),(-1,0,3),(x,-3,0)] is a skew - symmetric matrix is _____________.

If the trace of the matrix A=({:(x-5,0,2,4),(3,x^(2)-10,6,1),(-2,3,x-7,1),(1,2,0,-2):}) assumes the value zero, then the value of x equals to
