Coefficient

Initial Definition

Coefficient usually refers to "numerical coefficient", even though the term has a broader definition.

Numerical Coefficient

A numerical coefficient is a constant multiplier of the variables in a term.

- In the term -5x
^{2}y, the numerical coefficient is -5. - In the expression ax
^{2}+ bx + c, the numerical coefficient of the x^{2}term is "a" and the numerical coefficient of the x term is "b". "c" is properly referred to as the constant term.

Coefficient (general)

A coefficient (in general) is any of the factors of a term relative to a given factor of the term.

- In the term -5x
^{2}y, the coefficient of "y" is -5x^{2}. - In the term -5x
^{2}y, the coefficient of "x^{2}" is -5y. - In the term -5x
^{2}y, the coefficient of "x^{2}y" is -5.
