here's what I've done
-got transpose of A
|-3 0 0 1 |
| 1 -2 1 0 |
| 2 -3 2 1 |
| 1 2 -1 2 |
the deteminant = 8 therefore (its's invertible)
**the problem***
|-3 0 0 1 | 1 0 0 0 |
| 1 -2 1 0 | 0 1 0 0 |
| 2 -3 2 1 | 0 0 1 0 |
| 1 2 -1 2 | 0 0 0 1 |
i've tried reducing this (even tried using adjoint method)
but i keep getting a different answer
could someone please post for me the row reductions to
get the inverse to this thing i.e
row2 -row3 on row3 etc etc etc .
