If the matrix A=[[8,-6,2],[-6,7,-4],[2,-4,lambda]] is singular then lambda is

If the matrix A=[(8,-6,2),(-6,7,-4),(2,-4,lamda)] is singular one, then lamda is

If the matrix [[0,1,-2],[-1,0,3],[lambda,-3,0]] is singular,then lambda=

I: If the matrix A =[(8,-6,2),(-6,7,-4),(2,-4,lamda)] is singular one, then lamda=3 II: If the matrix [(cos theta, sin theta, 0),(sin theta, cos theta, 0),(0,0,1)] is singular then theta=pi//2

Find eigen-values for the matrix [[8,-6,2-6,7,-42,-4,3]]

If [[3,5,3],[2,4,2],[lambda,7,8]] is a singular matrix, write the value of lambda.

If the matrix [(1,2,-1),(-3,4,k),(-4,2,6)] is singular, then the value of k is equal to
