Important Terms about Polynomials
  • A combination of constants and variables, connected by four fundamental arithmetical operations +, -, x and / is called an algebraic expression. e.g. 6x² – 5y² + 2xy
  • An algebraic expression which have only whole numbers as the exponent of one variable, is called polynomial in one variable. e.g. 3x³ + 2x² – 7x + 5 etc.
  • The part of a polynomial separated from each other by + or – sign is called a term and each term of a polynomial has a coefficient.
  • Highest power of the variable in a polynomial, is known as degree of that polynomial.



  • On the Basis of Number of Terms
    1. A polynomial containing one non-zero term, is called a monomial.
    2. A polynomial containing two non-zero terms, is called a binomial.
    3. A polynomial containing three non-zero terms, is called a trinomial.
  • On the Basis of Degree of Variables
    1. A polynomial of degree 0, is called a constant polynomial.
    2. A polynomial of degree 1, is called a linear polynomial.
    3. A polynomial of degree 2, is called a quadratic polynomial.
    4. A polynomial of degree 3, is called a cubic polynomial.
    5. A polynomial of degree 4, is called a biquadratic polynomial.
  • The value obtained on putting a particular value of the variable in polynomial is called value of the polynomial at the value of variable.
  • Zero of a polynomial p(x) is a number alpha, such that p(alpha) = 0. It is also called root pf polynomial equation p(x) = 0.




  • Let f(x) be any polynomial of degree n,(n ≥ 1) and a be any real number. If f(x) is divided by the linear polynomial (x-a), then the remainder is f(a).
  • Let f(x) be a polynomial of degree n,(n ≥ 1) and a be any real number. Then,
    1. If f(a) = 0, then (x – a) is a factor of f(x).
    2. If (x – a) is a factor of f(x), then f(a) = 0.
