Question

Math help, I think this problem has something to do with the rational root, theorem, but am not sure.

Answer 1

yes, you're on the right track. you'd use the rational root theorem, listing:

p (all the factors of the constant term)
and q (all the factors of the leading coefficient)

then list all possible combinations of +/- (p/q), reducing fractions as needed, and making sure you only report each unique value once.

Answer 2

when you say list all possible combinations of p/q, do you mean putting only the p factors on the numerator, and only q factors in the denominator?

Answer 3

yes

Answer 4

okay, I did all that I think, but I got .9 out of one credit for the answer, what did I miss:

Answer 5

wait actually I see now, I forgot to reduce +-2/9

Answer 6

I should have omitted +-2/9

Answer 7

and the 4/9 as well
