"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)).
