I have no idea what you are doing. Are those vectors or matrices or what ?
There Matrices , Sorry I don't know how to type it on the laptop
can you describe it in words?

is it a single matrix like
| -8 +4 |
| +0 +3 |
| +6 +3 |

and you want something about it ?
Anyway --- go here :

http://matrixcalc.org/en/
it has a -3 on the outside of it

|-8 4|
-3|0 -1|
|6 3|
That's how it looks
well it didn't come out right again but thank you anyway , Ill check at out rigt now
Oh like this?

| -8 +4 |
-3| +0 +3 |
| +6 +3 |

now does it want the product or -3 times the determinant I wonder ?
what am I supposed to type in matrix b ?
Perhaps nothing. I need to figure out what the question is :)
it just says what does it equal
That's the question , but you wrote +3 twice , the middle one is -3|0-1|
Well, if you multiply a matrix by a scalar, you multiply every element by the scalar
|24 -12|
|0 +3 |
|-18 -9|
