A coefficient is a number paired with a variable. For example, in the equation

4x+2x=16, the numbers 4 and 2 would be coefficients.

Coefficients are the factors (usually constants) which are multiplied by the variables in each term. For example, in a second-degree polynomial equation,

y = ax2 + bx + c

a is called the quadratic coefficient, b is the linear coefficient and c is the constant term.
