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
