A =
(a b c)
(x y z)
...
They won't always line up, but it should be decipherable.
The A= has to be on its own line, because it would get in the way of the first row.
If it's an inverse, you might try
(1 2 3)
(4 5 6) ^-1
Thanks let me try
Given that A=(1 5)(3 7) and that B=(7 3)(-4 -2) and that C=AB.Find C-1.Solve for the unknown given that the following is a singular matrix.(1 2)(x x-3)
If (1 2)(x x-3) is singular, then
|1 2|
|x x-3| = 0
so
1(x-2)-2x = x-2-2x = -x-2 = 0
x = -2

C = AB =
(-13 -7)
(-7 -5)
So, C-1 =
(-5/16 7/16)
(7/16 -13/16)

Or, you can find A-1 and B-1
and then C-1 = (AB)-1 = B-1A-1
oops
x-3-2x = 0
x = -3
x-3x-2x i hav gotten till there but am trying to get how u got x=-3
huh? This is Algebra I
x-3-2x = 0
-x-3 = 0
x = -3
