Example1. Find Expanding determinant along row / column ...
`[[8,-6,2],[-6,7,-4],[2,-4,3]]`
Expanding determinant along row 2Solution:| `|A|` | = | | `8` | `-6` | `2` | | | `-6` | `7` | `-4` | | | `2` | `-4` | `3` | |
|
`=6 xx (-6 xx 3 - 2 xx (-4))+7 xx (8 xx 3 - 2 xx 2)+4 xx (8 xx (-4) - (-6) xx 2)` `=6 xx (-18 +8)+7 xx (24 -4)+4 xx (-32 +12)` `=6 xx (-10)+7 xx (20)+4 xx (-20)` `=-60+140-80` `=0` |
