Rational root theorem  Wikipedia
https://en.wikipedia.org/wiki/Rational_root_theorem
In algebra, the rational root theorem (or rational root test, rational zero theorem, rational zero test or p/q theorem) states a constraint on rational solutions of a polynomial equationwith integer coefficients and . Solutions of the equation are also called roots or zeroes of the polynomial on the left side. The theorem states that each rational solution x = ⁄q, written in lowest terms so that p and q are relatively …

The Rational Root Theorem
http://wmueller.com/precalculus/families/ratroot.html
The importance of the Rational Root Theorem is that it lets us know which roots we may find exactly (the rational ones) and which roots we may only approximate (the irrational ones). Here is how it works. Consider the polynomial P(x) = x 3 – 8 x 2 + 17 x – 10. In this case, a 0 = –10 and a n = 1 . The number –10 has factors of {10, 5, 2, 1} .

What exactly is a rational root?
https://www.britannica.com/science/rationalroottheorem
Rational root theorem, also called rational root test, in algebra, theorem that for a polynomial equation in one variable with integer coefficients to have a solution (root) that is a rational number, the leading coefficient (the coefficient of the highest power) must be divisible by the denominator of the fraction and the constant term (the one without a variable) must be divisible by the numerator.

How do you find rational roots?
https://www.britannica.com/science/rationalroottheorem
Finding the rational roots (also known as rational zeroes) of a polynomial is the same as finding the rational xintercepts. Start by identifying the constant term a0 and the leading coefficient an. Determine the positive and negative factors of each.
