rational zeroes

[sicsniper911]

What are all the possible rational zeros for f(x) = x^3 + 8x + 6? i have no idea what a rational zero is or what to do with one. please help.

f(x) = x^3 + 8x + 6

Consider the factors of 6 {p}: ±1, ±2, ±3, ±6
Now the factors of 1{q}: ±1

Form rational numbers p/q: ±1, ±2, ±3, ±6

These are the possible rational zeros of f(x).

By the way, I find there are no rational zeros for f(x).
