Question

write a list of potential rational zeros:
f(x)=3x^2-x+9

Answer 1

the find the factors of the constant term call them p

\[\pm 1, \pm 3, \pm 9\]

find the factors of the coefficient of x^2 call them q

\[\pm 1, \pm 3\]

the possible rational zeros will be p/q

Answer 2

wait... i dont get you.

Answer 3

well the rational zeros may be 1/1, -1/1, 1/-1 or -1/-1, or 1/3, -1/3, 1/-3 or -1/-3

as you can see ther double up

so its 1, -1, -1/3 1/3 etc
