# Polynomials Terms

## Get down with the lingo

### Algebraic Expressions

An expression that contains one or more terms and operations to combine them. Each term contains variable(s), constant(s), or a product of variables and constants.### Coefficient

The number being multiplied by a variable. Coefficients give regular old variables a little boost! For example, the coefficient in 3*x*is 3.

### Constant

A value that does not change.### Dependent Variables

A variable in a function that changes due to the independent variable.### Equations

An expression that states the equation of two algebraic expressions.### Equivalent Equations

Two different pairs of equations that have the same solution(s).### Factoring

Breaking a polynomial into two or more expressions that can be multiplied together to get the original polynomial. Basically, it's like reverse-distributing.### Formulas

Determines the relationship between two or more variables.### Independent Variables

Variables in a function that assume values freely or independently.### Inequality

A relation between two algebraic expressions using the symbols <, >, ≤, and ≥.### Like Terms

Two terms that have the same variables raised to the same exponent. Like terms may have different coefficients.### Parentheses

### Quadruple

Four times a number.### Perimeter

The length of the boundary of a closed shape.### Rectangle

A parallelogram with all angles equal to 90°.### Solution

The value(s) of variable(s) that satisfy an equation or inequality.### Square

A parallelogram with all angles equal to 90° and all sides equal in length.### Trapezoid

A four-sided closed shape with straight lines and only one pair of opposite sides equal in length.### Triangle

A three-sided closed shape with straight lines.### Variable

A value that changes. Variables are commonly represented by the letters*x*,

*y*or

*z*.
