polynomial
Meaning: A mathematical expression consisting of variables, coefficients, and non-negative integer exponents, combined using addition, subtraction, and multiplication. Examples include x^2 + 3x + 5.
Polynomials are classified by their degree (the highest exponent): linear (degree 1), quadratic (degree 2), cubic (degree 3), and so on. They are among the most studied objects in algebra and appear throughout science and engineering for modelling relationships. 'Polynomial time' in computing describes algorithms whose running time grows manageably with input size. It collocates with 'equation,' 'function,' 'degree,' 'root,' and 'expression.'
Examples
- The polynomial x^3 - 2x + 1 has a degree of three, making it a cubic expression. 多项式x³ - 2x + 1的次数为3,属于三次表达式。El polinomio x³ - 2x + 1 tiene grado tres, lo que lo convierte en una expresión cúbica.多項式x³ - 2x + 1は次数が3であり、三次式です。다항식 x³ - 2x + 1은 차수가 3이므로 삼차식입니다.
- Factoring a polynomial into simpler components is a fundamental skill in algebra. 将多项式分解为更简单的因式是代数中的一项基本技能。Factorizar un polinomio en componentes más simples es una habilidad fundamental en álgebra.多項式をより単純な因子に分解することは、代数の基本的なスキルです。다항식을 더 단순한 인수로 분해하는 것은 대수학의 기본 기술입니다.
- The algorithm runs in polynomial time, making it efficient for large data sets. 该算法在多项式时间内运行,使其对大数据集的处理非常高效。El algoritmo se ejecuta en tiempo polinómico, lo que lo hace eficiente para conjuntos de datos grandes.このアルゴリズムは多項式時間で動作するため、大規模なデータセットに対して効率的です。이 알고리즘은 다항식 시간으로 실행되므로 대규모 데이터 세트에 효율적입니다.
