# Algebra 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

### 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 up an algebraic expression into two or more expressions that can be multiplied together to get the original expression.

### 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 unequal 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*.
