A coefficient is a constant multiplier of variables and any part of an algebraic term, Thus, in the expression
the possible coefficients for the term 3xy2 would include 3, which is the coefficient of xy2, and x, which is the coefficient of 3y2:
has 4 as a coefficient of
Most commonly, however, the word coefficient refers to what is, strictly speaking, the numerical coefficient. Thus, the numerical coefficients of the expression 5xy 2 - 3x + 2y - 4-X are considered to be 5, -3, +2, and -4.
