Decide c, so that A(2)X=b(c) where
x=(x,y,z) and b(c)=(1,c,1)
A(2) is calculated from the previous problem:
"Decide the value on the parameter b so that the following system has solutions
1, 2, 2, 2b
The Attempt at a Solution
Alright, I solved the previous problem that is stated and I got the answer to be b=-1/2
but from that, what do I do? The real question is, what does A(2)x mean? I substitute b for 2?
