[snip] A = 1 B+A*R = 9 C+B*R+A*R^2 = -7 I get (b/3) + 3 - (7/3b) when I work it out by hand, and a teacher of mine got the same thing. What exactly is this program finding, since it obviously isn't any coefficients? [/snip]
Acutally, looking at it further, it looks like it actually almost did it correctly. If you take the results that the calculator gave you and divide them by 3 then you get your answer. So the caluclator divides it by b then you have to add in a part of it to divide by the 3.
