Now get the values of A, B and C:
Substitute x = -1: 1 = C.
Substitute x = 0: -1 = B.
Substitute x = 1: 5 = 2A + 2B + C => A = 3 (using the known values of B and C).
At all. I have a test on it tomorrow, and this is mightily distressing, to say the least.
If someone could give me clear instructions on how to solve these kinds of problems?
Or give clear steps on how to solve this:
Thank you ahead of time for any help!
