First of all, to have an inverse the matrix must be "square" (same number of rows and columns). But also the determinant cannot be zero(or we end up dividing by zero). How about this: 24−24? That equals 0, and 1/0 is undefined. We cannot go any further! This matrix has no Inverse. Such a matrix is called … See more
