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 Fundamental Theorem of Algebra (代数基本定理) If f(x) is a polynomial of degree n, where n≥1, then the equation f(x)=0 has at least one complex root. Proof: f(x)=0 has at least one complex root c_{1} . By the Factor theorem, x-c_{1} is a factor of f(x) (x...
Specifically, we prove that in the context of the equation's associated planar mapping , if is a rational invariant then for some real number 位. Thus, I is constant and hence trivial. The proof is an induction based on a strict linear ordering of the coefficients of P and Q.doi:...

Theorem 1.8.1 The square root of 2 is not a rational number, i.e. 2 ∉ ℚ. Proof Suppose that 2∈ ℚ. Then there exist k∈ ℤ and n∈ ℕ such that 2 = k/n and k and n have no common factor. [If necessary, we can cancel any common factors to achieve this.] Then...
