My expression is -5x+4-x-1

## How do you identify terms, like terms, coefficients, and constants in expressions?

# 1 Answer

According to Wikipedia,"A term is a mathematical expression that may form a separable part of an equation, a series, or another expression."

In this case, the terms are **-5x, 4, -x** and **-1**. These can also be referred to as monomials.

Like terms are the parts of the polynomial that are similar in degree. For example,
**-5x** and **-x** are like terms, because they both have x in the term.
**4** and **-1** are also like terms because they are both constants.

Constants are terms where the value never changes. 4 is always equal to 4, and -1 is always equal to -1, so their values are constant.

Coefficients are the factors in the terms (or monomials) that are constant, that is, are not the variable. For example,
**-5** is the coefficient of **-5x**, and **-1** is the coefficient of
**-x** .
