What is a coefficient?

Answer 1

A coefficient is a number in front of a variable (i.e. multiplied by it).

For example, in the expression x2 - 10x + 25, the coefficient of x2 is 1 and the coefficient of x is -10. The third term, 25, is a constant.

If the expression were -x2 + 10x + 25, the coefficient of x2 would be -1, and the coefficient of x would be 10.

Answer 2

A coefficient is a numerical or constant factor in front of a variable in an algebraic expression. It indicates the amount or degree of change in the variable. For example, in the expression 3x, the coefficient is 3.

Answer 3

The numerical part of a term that contains a variable.
