Coefficients

In mathematics, a coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression. It is the number that is being multiplied by a variable. For example, in the expression 3x, the coefficient is 3.

Study Guide

Here are some key points to remember about coefficients:

1. Definition: A coefficient is the numerical factor in a term. It is the number that is being multiplied by a variable.
2. Example: In the expression 5y, the coefficient is 5.
3. Variables: Coefficients can be attached to one or more variables in an algebraic expression. For example, in the expression 2xy, the coefficient is 2.
4. Constant Term: In a polynomial, the term without a variable has a coefficient known as a constant term. For example, in the expression 4, the coefficient is 4.
5. Importance: Understanding coefficients is important in simplifying algebraic expressions, solving equations, and graphing linear equations.

Remembering these key points will help you understand and work with coefficients in algebraic expressions and equations.

Practice identifying coefficients and working with them in different algebraic expressions to strengthen your understanding of this concept.
