polynomial

A student graphs a polynomial on the coordinate plane.

Definition
  1. Adjective:

    • Having the character of or relating to a polynomial: Describes an expression, equation, or function that is or can be expressed as a polynomial.
  2. Noun:

    • A mathematical expression: A function that is the sum of a finite number of terms, where each term consists of a constant coefficient multiplied by a variable raised to a non-negative integer power.
Usage Examples
  • Adjective:

    • The equation is a polynomial equation of degree three.
    • We need to simplify this polynomial expression.
  • Noun:

    • The function f(x) = 3x² + 2x - 5 is a polynomial.
    • Solving this polynomial requires finding its roots.
Advanced Usage
  • "Polynomial time": In computer science, refers to an algorithm whose running time is bounded by a polynomial expression in the size of the input.

    • Problems solvable in polynomial time are generally considered tractable.
  • "Polynomial regression": A form of regression analysis where the relationship between variables is modeled as an nth degree polynomial.

    • We used polynomial regression to fit a curve to the data points.
Variants and Related Words
  • Polynomial function (n): A function defined by a polynomial expression.

    • A quadratic function is a specific type of polynomial function.
  • Monomial (n): A polynomial with only one term (e.g., 5x³).

  • Binomial (n): A polynomial with exactly two terms (e.g., x + 1).
  • Trinomial (n): A polynomial with exactly three terms (e.g., x² + 2x + 1).
Synonyms
  • Multinomial (n): A less common synonym for a polynomial, especially one with multiple terms.
  • Algebraic expression (n): A broader category that includes polynomials.
Related Phrases and Concepts
  • Degree of a polynomial: The highest power of the variable in the polynomial.

    • The degree of the polynomial x⁴ + 2x is four.
  • Coefficient of a polynomial: The constant number multiplying a variable term.

    • In the term 7x², the coefficient is 7.
  • Root/Zero of a polynomial: A value for the variable that makes the polynomial equal to zero.

    • Finding the roots of the polynomial is a key task in algebra.
