Note that for each the matrix on the right differs from the one on the left by a small number of elementary row/ column operations. For these, you should not calculate the determinant, but instead should figure out which operations it took to get from one matrix to the other and determine how that effects the value of the determinant. -1 2 -1 2 3 O det( 2 - 2 -1 ) = det( 2 - 2 - 3 0 3 1 0 3 4 2 -18 167 -9 8 Odet( ( 0 -4 6 ) = 2*det(|0 -2 3) 0 -6 8 0 -3 4 -4 -8 37 -5 -8 37 O det( -5 -8 3 ) = -1*det( 8 3 ) -1 -3 1 09 1 Add Work
