Identifying Constants, Coefficient, Powers

 

About

Each expression is made up of terms.

A term can be

  • a signed number
  • a variable
  • a constant multiplied by a variable
  • Variables.

Each term in an algebraic expression is separated by a 1 sign or 2 sign.

Example: 6x, 7y, and 8

When a term is made up of a constant multiplied by a variable or variables, that constant is called a coefficient. In the term 7x, the coefficient is 7.
