factorisable
含义: Capable of being expressed as a product of simpler factors. In mathematics, describes a number, polynomial, or expression that can be broken down into a multiplication of its components.
Factorisable (spelled 'factorizable' in American English) is primarily a mathematical term but appears in broader analytical writing when discussing anything that can be decomposed into contributing elements. In number theory, every integer greater than one is factorisable into primes — this is the fundamental theorem of arithmetic. In algebra, determining whether a polynomial is factorisable over a given field is a central problem. The word implies analytical tractability and structural transparency.
例句
- The quadratic expression is readily factorisable, yielding two linear factors with integer coefficients. 这个二次表达式容易因式分解,得出两个整数系数的一次因式。La expresión cuadrática es fácilmente factorizable y produce dos factores lineales con coeficientes enteros.この二次式は容易に因数分解でき、整数係数の2つの一次因子が得られる。이 이차식은 쉽게 인수분해할 수 있으며, 정수 계수를 가진 두 개의 일차 인수가 얻어진다.
- Not every polynomial with rational coefficients is factorisable over the rationals, as the case of x² + 1 illustrates. 并非所有有理系数多项式在有理数域上都是可因式分解的,x²+1就是一个例子。No todos los polinomios con coeficientes racionales son factorizables sobre los racionales, como ilustra el caso de x² + 1.有理数係数のすべての多項式が有理数体上で因数分解可能なわけではなく、x²+1がその例である。유리수 계수를 가진 모든 다항식이 유리수체 위에서 인수분해 가능한 것은 아니며, x²+1이 그 예이다.
- The encryption scheme relies on the assumption that very large numbers are not efficiently factorisable by classical computers. 该加密方案依赖于一个假设,即非常大的数不能被经典计算机高效地分解因式。El esquema de cifrado se basa en la suposición de que los números muy grandes no son factorizables de manera eficiente por ordenadores clásicos.その暗号方式は、非常に大きな数が古典的なコンピュータでは効率的に因数分解できないという仮定に基づいている。그 암호 체계는 매우 큰 수가 고전적 컴퓨터로는 효율적으로 인수분해될 수 없다는 가정에 기반하고 있다.

起源与历史
From Latin factor (maker, doer), from facere (to make, do), combined with the English suffix -isable. The British spelling with -ise follows standard convention; the mathematical usage dates from the 19th century.
