Algebraic ExpressionsAn 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.
CoefficientA number or a constant multiplied to a term in an algebraic expression.
ConstantA value that does not change.
Dependent VariablesA variable in a function that changes due to the independent variable.
EquationsAn expression that states the equation of two algebraic expressions.
Equivalent EquationsTwo different pairs of equations that have the same solution(s).
FactoringBreaking up an algebraic expression into two or more expressions that can be multiplied together to get the original expression.
FormulasDetermines the relationship between two or more variables.
Independent VariablesVariables in a function that assume values freely or independently.
InequalityA relation between two unequal algebraic expressions using the symbols <, >, ≤, and ≥.
Like TermsTwo terms that have the same variables raised to the same exponent. Like terms may have different coefficients.
ParenthesesBrackets used in pairs to group things together.
QuadrupleFour times a number.
PerimeterThe length of the boundary of a closed shape.
RectangleA parallelogram with all angles equal to 90°.
SolutionThe value(s) of variable(s) that satisfy an equation or inequality.
SquareA parallelogram with all angles equal to 90° and all sides equal in length.
TrapezoidA four-sided closed shape with straight lines and only one pair of opposite sides equal in length.
TriangleA three-sided closed shape with straight lines.
VariableA value that changes. Variables are commonly represented by the letters x, y or z.
