Rational Root Theorem: Suppose that a polynomial equation with integral coefficients has the root p/q , where p and q are relatively prime integers. Then p must be a factor of the constant term of the polynomial and q must be a factor of the coefficient of the highest degree term. (usef...
The rational zero theorem is a very useful theorem for finding rational roots. It states that if any rational root of a polynomial is expressed as a fraction pq in the lowest terms, then p will be a factor of the constant term and q will be a factor of the leading coefficient. ...
A real number β is a Pisot number if β>1 and β is the root of a monic polynomial in integer coefficients, such that all its conjugate values (that is, all the other roots of its minimal polynomial) have absolute values strictly less than 1. This purely algebraic condition is interest...
What is the rational zero theorem?Zeros of a Polynomial:Polynomial is a summation of algebraic terms known as monomials, which have coefficient, variable, and exponent. They have the form {eq}(ax^{n}) {/eq}. The zeros of a polynomial {eq}S(x) {/eq} are those values of the ...

Denote by ⁎q⁎ the conjugate quaternion and by N:H→R≥0, ⁎q↦qq⁎ the quaternion norm function. Extending it to a map from H[t] into the set of positive univariate polynomials, Equation (1) then becomes N(F(t))=σ2(t). Let us recall the following definition (first pre...
