E21 subtracts 5 times row 1 from row 2
WebE subtracts 5 times row 1 from row 2. Then F subtracts 4 times the new row 2 (changed by row 1) from row 3. In this order FE, row 3 feels an effect of size 20 from row 1. In the order E−1F−1, that effect does not happen. First F−1 adds 4 times row 2 to row 3. After that, E−1 adds 5 times row 1 to row 2. There is no 20, because row 3 ... Web1 Write down the 3 by 3 matrices that produce these elimination steps: (a) E21 subtracts 5 times row 1 from row 2. (b) E32 subtracts -7 times row 2 from row 3. (c) P exchanges rows 1 and 2, then rows 2 and 3. 63 2 In Problem 1, applying E21 and then E32 to b = (1,0,0) gives E32E21b = __ Applying E32 before E21 gives E21 E 32 b .
