For example, the polynomial has coefficients 2, -1, and 3, and the powers of the variable in the polynomial have coefficient parameters , , and .

A , also known as constant term or simply constant, is a quantity either implicitly attached to the zeroth power of a variable or not attached to other variables in an expression; for example, the constant coefficients of the expressions above are the number 3 and the parameter c, involved in 3cx⁰. The coefficient attached to
