factorisation
Học thuậtThân thiện
A student writes the factorisation of a quadratic equation on the chalkboard.
Definition
Noun: 1. (Mathematics): The process or result of breaking down a mathematical expression (such as a number or a polynomial) into a product of simpler factors. These factors, when multiplied together, yield the original entity.
Usage
- General Use: The term is used almost exclusively in mathematical contexts to describe the decomposition of an entity into its constituent multiplicative components.
- The teacher explained the factorisation of quadratic equations.
- Prime factorisation is a fundamental concept in number theory.
Advanced Usage
- Polynomial Factorisation: The process of expressing a polynomial as a product of its factors, which may be other polynomials or constants.
- The factorisation of
x² - 4results in(x - 2)(x + 2).
- Integer Factorisation (or Factorization): The decomposition of a composite number into a product of smaller integers, particularly prime numbers.
- The security of some encryption systems relies on the difficulty of integer factorisation.
Variants and Related Words
- Factor (verb): To resolve or break down into factors.
- We need to factor this polynomial.
- Factorization (noun): An alternative spelling, primarily used in American English.
- Factorable (adjective): Capable of being factored.
- Not all polynomials are factorable using real numbers.
Synonyms
- Decomposition (in a mathematical context)
- Resolution into factors
- Factoring (often used as a gerund to describe the process)
Notes on Different Meanings
The word 'factorisation' is highly specialized. It does not have common non-mathematical meanings, idiomatic uses, or associated phrasal verbs. Its usage is confined to technical discussions in mathematics and related fields like cryptography.
