binomial

polynomial with two terms


closed interval

an interval that includes its endpoints


compound inequality

two inequalities combined using either "and" (a conjunction) or "or" (a disjunction


degree of the polynomial

largest degree of a polynomial's terms


dependent system of equations

a system of equations with infinitely many possible choices


discriminate

for quadratic equation in standard form the discriminate is b 4 ac


domain (of a relation or function)

the set of all possible "input" into a unique "output"


factoring

writing a polynomial as a product of two or more factors


factor

a number or expression that can be multiplied to get another number or expression e.g. two is a factor of 6 becuase 2x3=6


function

a rule for transforming any "input" into a unique "output"


greatest common factor (GCF)

largest expression that is a common factor of two or more expressions


additive identity

0 is the additive identity because it can be added to any number without changing it


multiplicative identity

1 is the multiplicative identity because any number can be multiplied by one without changing it


inconsistent systems of equations

the system of equations with no solutions


least common multiple (LCM)

the smallest expression that has two or more other expressions as factors


monomial

expression with a single term


numeric expression

a number or any expression containig only numbers (no variables)


open interval

an interval that does not contain its endpoint


polynomial

a monomial or sum of monomials


radicand

the number inside a radical symbol


range (of a relation or function)

the set of all possible "outputs" of the relation or function. (y)


rational expression

expression written as a fraction


relation

any set of ordered pairs ( the first number or expression is the relations "inputs," the second is the "output"


route of an equation

in equations roots are solutions


trinomial

a polynomial with three terms


zero product property

if the product of two factors is zero, then at least one of the factors must itself be zero
