A polynomial is..

• a multiplicative factor in some term of a polynomial, a series, or any expression; it is usually a number, but may be any expression

• a symbol, commonly a single letter, that represents a number,

• terms are terms that have the same variables and powers

• an expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables. From the latin for "many terms"

A coefficient is..

• a number multiplied (and attached) in some term of a polynomial, a series, or any expression; it is usually a number attached to a variable

• a symbol, commonly a single letter, that represents a number,

• terms are terms that have the same variables and powers

• an expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables. From the latin for "many terms"
