Term | Definition |
---|---|
monomial | a number, a variable, or a product of a number and one or more variables with whole number exponents |
degree of a monomial | the sum of the exponents of the variables in a monomial |
polynomial | a monomial or a sum of monomials; each monomial is called a term of the polynomial |
binomial | a polynomial with two terms |
trinomial | a polynomial with three terms |
degree of a polynomial | the greatest degree of the terms of a polynomial |
FOIL method | a shortcut for multiplying two binomials |
factored form | a polynomial is in factored form when it is written as a product of factors |
zero-product property | if the product of two real numbers is 0, then at least one of the numbers is 0 |
roots | the solutions of a polynomial equation |
factoring by grouping | to factor polynomials with four terms, group the terms into pairs, factor the GCF out of each pair for the terms, and look for a common binomial factor |
prime polynomial | a polynomial that cannot be factored as a product of polynomials with integer coefficients |
factored completely | a factorable polynomial with integer coefficients is said to be factored completely when no more factors can be found and it is written as the product of prime factors |
