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.
CoefficientThe number being multiplied by a variable. Coefficients give regular old variables a little boost! For example, the coefficient in 3x is 3.
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 a polynomial into two or more expressions that can be multiplied together to get the original polynomial. Basically, it's like reverse-distributing.
FormulasDetermines the relationship between two or more variables.
Independent VariablesVariables in a function that assume values freely or independently.
InequalityA relation between two 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.
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.
