Hey guys i am stuck with the gaus jordan method of the following matrix.(adsbygoogle = window.adsbygoogle || []).push({});

A = 1 2 3

4 5 6

3 1 -2

For the co factor i worked out the C transpose as:

1/3 (-16 7 3

26 -8 6

-11 5 -3)

The gaus jordan is suppoesed to agree with my final cofactor matrix but i cant seem to understand how to get there?? i have donw the row eliminations to get the diagonal as 1 and the rest as 0.

Add (-4 * row1) to row2

Add (-3 * row1) to row3

Divide row2 by -3

Add (5 * row2) to row3

Divide row3 by -1

Add (-2 * row3) to row2

Add (-3 * row3) to row1

Add (-2 * row2) to row1

But now i don't understand what i have to do now?
