User: What does coefficient mean?

Weegy: In mathematics, a coefficient is a multiplicative factor in some term of an expression (or of a series); it is usually a number, but in any case does not involve any variables of the expression. [ For instance in 7x2 - 3xy + 1.5 + y the first three terms respectively have the coefficients 7, -3, and 1.5 (in the third term there are no variables, so the coefficient is the term itself; it is called the constant term or constant coefficient of this expression). The final term does not have any explicitly written coefficient, but is usually considered to have coefficient 1, since multiplying by that factor would not change the term. ]

= 5(-xy + y) - 2x(y - x) + y(x + y)
= -5xy + 5 - 2xy - 2x + yx + y^2
= y^2 -6xy - 2x + 5
