Polynomial: A mathematical expression made up of monomials, each of which is composed of a numerical coefficient and a variable raised to a power. Monomial: 1 term Binomial: 2 terms Trinomial: 3 terms Degree of a Polynomial: The highest power of the variable in a polynomial expression, which determines the number of terms in the polynomial. Term: Each monomial in a polynomial that is separated between plus or minus signs. Coefficient: The numerical factor that multiplies the corresponding variable in a polynomial expression.

The oldest known polynomial equation dates back to Babylonian clay tablets from over 3,500 years ago. The expression “binomial coefficient” is a combination of two Latin words, “bi” which means two, and “nomen” which means name Every polynomial equation of degree n has at most n distinct roots or solutions
