• A monomial is an expression that is either a
  number, a variable, or the product of a number
  and one or more variables.
• A binomial, such as x 4, is the sum of two
  monomials.
• A trinomial, such as x2 11x 28, is the sum of
  three monomials.
• A polynomial is a monomial or a sum of monomials,
  each of which is called a term of the polynomial.
