Hi;
When determining rational roots of a polynomial ie b/c or b/q which one is correct
and what do the letters mean?
Thanks,
most texts use $\displaystyle \frac{p}{q}$, though it doesn't really matter what letters are used ...
Mathwords: Rational Root Theorem
For a polynomial in the form $\displaystyle a_n x^n + a_{n-1}x^{n-1} + \dots + a_1x + a_0 = 0$, where $\displaystyle a_i \in \mathbb{Z}$, all possible rational roots are in the form $\displaystyle \frac{p}{q}$, where $\displaystyle p$ is a factor of the constant coefficient $\displaystyle a_0$ and $\displaystyle q$ is a factor of the leading coefficient $\displaystyle a_n$. Very easy to prove.
