Polynomials in One Variable

If there is only one variable in the expression then this is called the polynomial in one variable.


  • x3 + x – 4 is polynomial in variable x and is denoted by p(x).
  • r2 + 2 is polynomial in variable r and is denoted by p(r).
  • A polynomial of degree 1 is called as a linear polynomial.
  • A polynomial of degree 2 is called a quadratic polynomial.
  • A polynomial of degree 3 is called a cubic polynomial.
  • A polynomial of 1 term is called a monomial.
  • A polynomial of 2 terms is called binomial.
  • A polynomial of 3 terms is called a trinomial.
