1. Example `[[8,-6,2],[-6,7,-4],[2,-4,3]]`
1. Find Transforming matrix to Row Echelon Form ... `[[8,-6,2],[-6,7,-4],[2,-4,3]]`
Solution: Row echelon form Given matrix
| | `8` | `-6` | `2` | | | `-6` | `7` | `-4` | | | `2` | `-4` | `3` | |
|
`R_1 larr R_1-:8`
= | | `1` | `-3/4` | `1/4` | | | `-6` | `7` | `-4` | | | `2` | `-4` | `3` | |
|
`R_2 larr R_2+6xx R_1`
= | | `1` | `-3/4` | `1/4` | | | `0` | `5/2` | `-5/2` | | | `2` | `-4` | `3` | |
|
`R_3 larr R_3-2xx R_1`
= | | `1` | `-3/4` | `1/4` | | | `0` | `5/2` | `-5/2` | | | `0` | `-5/2` | `5/2` | |
|
`R_2 larr R_2xx2/5`
= | | `1` | `-3/4` | `1/4` | | | `0` | `1` | `-1` | | | `0` | `-5/2` | `5/2` | |
|
`R_3 larr R_3+5/2xx R_2`
= | | `1` | `-3/4` | `1/4` | | | `0` | `1` | `-1` | | | `0` | `0` | `0` | |
