Hey y'all well I'm having major problems trying to figure out matrix determinants. I keep trying and trying but getting a totally diffrent answer from what the back of the book says...
[12, 4, -6]
[ 2, 1, 3 ]
[1, 0, -2 ]
I dont know if the way I typed that is understandable but that's the determinant which is a 3 x 3 and I'm supposed to evaluate it and everytime I try and evalute it, I always end up with -34 and the back of my book says the answer is 10 and I am so way totally stuck so if someone could help me, it would be greatly appreciated.
Thanks ~*
