Use the distributive property to write an expression equivalent to 14x 21y

If we add the number zero to the set of natural numbers, then we have a set of numbers that are called the whole numbers. The number 0 is special, in that whenever you add it to another whole number, you get the identical number as an answer. For this reason, the whole number 0 is called the additive identity.

Corporations all over the world sell enryption systems that are supposed to keep data seure and safe. Inthree professors from the Massahusetts Institute of Tehnology developed an enryption system they alled RSA, a name derived from the first letters of their last names.

Their seurity ode was based on a number that has digits. They alled the ode RSA For the ode to be broken, the digit number must be fatored into two prime numbers.

A data seurity ompany says that people who are using their system are safe beause as yet no truly effiient algorithm for finding prime fators of massive numbers has been found, although one may someday exist.

This ompany, hoping to test its enrypting system, now sponsors ontests hallenging people to fator more very large numbers into two prime numbers.

The answers for these exerises an be found in the bak of the text. If you are working on your own, or ahead of the lass, this pretest an help you identify the setions in whih you should fous more of your time.

Whether you are by nature gregarious or shy, you have muh to gain by getting to know your lassmates. It is important to have someone to all when you miss lass or are unlear on an assignment.

Working with another person is almost always benefiial to both people. If you don t understand something, it helps to have someone to ask about it. If you do understand something, nothing ements that understanding more than explaining the idea to another person.

Sometimes we need to ommiserate. If an assignment is partiularly frustrating, it is reassuring to find that it is also frustrating for other students.

Have you ever thought you had the right answer, but it doesn t math the answer in the text? Frequently the answers are equivalent, but that s not always easy to see.

A different perspetive an help you see that. Oasionally there is an error in a textbook here we are talking about other textbooks.

In suh ases it is wonderfully reassuring to find that someone else has the same answer you do. In Chapter 3 you were given fators and asked to find a produt. We are now going to reverse the proess. You will be given a polynomial and asked to find its fators. This is alled fatoring.

We start with an example from arithmeti. To multiply 5 7, you write To fator 35, you would write Fatoring is the reverse of multipliation. Now let s look at fatoring in algebra.

For instane, 3 x 5 3x 15 To use the distributive property in fatoring, we reverse that property as ab a a b The property lets us fator out the ommon fator a from the terms of ab a. To use this in fatoring, the first step is to see whether eah term of the polynomial has a ommon monomial fator.how to write algebraic expression for 5 times the difference of a number and twelve Rational expressions calculator, factoring polynomial solver, Math Problem Solver-distributive property, equation division calculator.

Example 1: Use the distributive law to remove the parenthesis form the expression 5(x + 3). Solution:Use the distributive Law5(x + 3) = = 5(x) + 5(3) 15x + 15 Example 2: Use the distributive law to remove the parenthesis form the expression 3(2x – 4y). Factoring (called "Factorising" in the UK) is the process of finding the factors: Factoring: Finding what to multiply together to get an expression. It is like "splitting" an expression into a multiplication of simpler expressions. To combine like terms, first use the commutative property to move all like terms together. Then, and asking them to write a term using the variables a, b, or a constant. For example, a student Simplify each expression by combining like terms. Find the answer at the bottom of the page.

A Factoring Out the Greatest Common Factor In this section we will apply the distributive property to polynomials to factor from them what is called the greatest common factor.

Definition The greatest common factor for a polynomial is the largest monomial that divides (is a . 8x3 x2 y · = 2 · x3+2 · y1−6 = 2x5 y−5 y6 4 You can also use the negative power rule the other way around if you want to write an expression without negative exponents.

Example C Write the following expressions without negative exponents. An expression is in simplest form if it is replaced by an equivalent expression with no like terms or parentheses.
