The rational root theorem (rational zero theorem) is used to find the rational roots of a polynomial function. By this theorem, the rational zeros of a polynomial are of the form p/q where p and q are the coefficients of the constant and leading coeffici
The rational root theorem is a theorem that you can use to find any rational roots of a polynomial equation.Rational root theorem Let anxn + an-1xn-1 + ... + a1x + a0 = 0 be a polynomial equation with integer coefficients. If p/q is in simplest form and is a rational root of...
(x)=0. The Rational Root Theorem ~ states that If P(x) is a polynomial with integer coefficients and if is a zero of P(x) then p is a factor of the constant term of P(x) and q is a factor of the leading coefficient of P(x). Using this theorem we can find all the ...

(Rational Root Theorem) 是试根法的一部分,用于简化试根法,帮助我们排除大部分不可能的值,减少计算量。因为是基础知识点,这里直接就给定义了: Letf(x)be the polynomialf(x)=anxn+an−1xn−1+an−2xn−2+...+a1x+a0, where all theaiare integers and bothananda0are nonzero. Ifpandqare ...
同理, q 是4 的约数。 考虑到 p,q 互质, q=\pm1 分别代入即可, q=1 时, a^2+4b^2+5=0 ,矛盾。 q=-1 ,也就是 a^2-4b^2+3=0 (2b+a)(2b-a)=3 (a,b)=(1,1),(-1,1),(-1,-1),(1,-1) 其实就是有理根定理了……详细请点进: 不用卡丹公式,一元三次方程如何巧解...
The theorem that, if a rational number p / q, where p and q have no common factors, is a root of a polynomial equation with integral coefficients, then the coefficient of the term of highest order is divisible by q and the coefficient of the term of lowest order is divisible by p.Mc...
