Polynomials
Vocabulary
Monomial | is a real number, a variable, or a product of real number and one or more variables with whole-number exponents. |
Degree of a Monomial | is a monomial or a sum of monomials. |
Polynomial | a polynomial that is written with the terms in order from greatest degree to least degree. |
Standard Form of a Polynomial | in one variable is the same as the degree of the monomial with the greatest exponent. |
Binomial | a polynomial with two terms which are not like terms |
Trinomial | a polynomial with three terms which are not like terms |
Greatest Common Factor (GCF) | The largest factor that two or more numbers have in common. |
Factor Out | "undistributing" by taking out the GCF. This rearranges the original expression but doesn't change it |
Distributive Property | a property indicating a special way in which multiplication is applied to addition of two or more numbers in which each term inside a set of parentheses can be multiplied by a factor outside the parentheses, such as a(b + c) = ab + ac |
F.O.I.L | Multiply each of the following terms in the binomials First Outside Inside Last |
The Square of a Binomial | the square of the binomial is the square of the first term plus twice the product of the terms plus the square of the last term (a + b)^2 = a^2 + 2ab + b^2 (a - b)^2 = a^2 - 2ab + b^2 |
The Product of the Sum and Difference | The product of the sum and difference of the same two terms is the difference of their squares (a + b)(a - b) = a^2 - b^2 |
Perfect Square Trinomial | it is the result of squaring a binomial |
Factoring by Grouping | If you factored trinomials of the form ax^2 + bx + c. by rewriting bx as a sum of two monomials. You then grouped the terms in pairs, factored the GCF from each pair and looked for a common binomial factor |
