3. Example `[[1,1,1],[-1,-3,-3],[2,4,4]]`
Find Upper Triangular Matrix ...
`[[1,1,1],[-1,-3,-3],[2,4,4]]`Solution:| `A` | = | | `1` | `1` | `1` | | | `-1` | `-3` | `-3` | | | `2` | `4` | `4` | |
|
`R_2 larr R_2+ R_1` | = | | `1` | `1` | `1` | | | `0` | `-2` | `-2` | | | `2` | `4` | `4` | |
|
`R_3 larr R_3-2xx R_1` | = | | `1` | `1` | `1` | | | `0` | `-2` | `-2` | | | `0` | `2` | `2` | |
|
`R_3 larr R_3+ R_2` | = | | `1` | `1` | `1` | | | `0` | `-2` | `-2` | | | `0` | `0` | `0` | |
|
| `:.U` | = | | `1` | `1` | `1` | | | `0` | `-2` | `-2` | | | `0` | `0` | `0` | |
