WebA zero matrix is just a matrix with any dimensions that has all elements inside the matrix as 0. It does NOT have to be a square matrix. 2. You are right. Sal could have multiplied a 2x2 zero matrix with the 2x3 matrix to obtain a resulting zero matrix. Having a 2x3 zero matrix makes no difference as having a 3x3 matrix. WebThe short answer is no, while it is true that row operations preserve the determinant of a matrix the determinant does not split over sums. We want to compute det (M-lambda I_n) which does not equal det (M)-det (lambda n). The best way to see what problem comes up is to try it out both ways with a 2x2 matrix like ( (1,2), (3,4)).
