Factoring can be used in laying a tile floor or packing various things into boxes. Also somewhat useful when changing screen resolutions. There is limited use in code breaking. Some things are useful as building blocks to bigger stuff. Other things will become useful later on, Microsoft Vista could be one of them. It is not used that much, not nearly as much as finding the greatest common divisor. We may find more uses later on, or not.

Factoring in real life

If you model some phenomenon with a polynomial, it's often of interest to determine when the polynomial evaluates to zero. One of the tools used in deciding when this happens is factoring.

For example, simple trajectory can be modeled with a quadratic function. If you think of time as the input and height as the output, then the positive time for which the polynomial evaluates to zero is precisely the time when the object hits the ground.

Factors in algebra are used almost all the time outside school. because factors tell you which numbers to multiply to give any  number you want. one simple example is  deciding how many soccer ball teams you can make from a group of 35 you can use the fact that 5 & 7 are two factors that make 35. In fact, any problem solving that requires you to group, divide and even rearrange shapes will involve knowing the factors that make up the numbers. The biggest advantage is that every number can be written as a multiplication  of  its factors. another way factors can be used is

Factoring polynomials in Real Life

Factoring Polynomials 

in Real Life

Three Examples:

1. You can use the concept of factoring binomials to figure out how long it takes a ball dropped from the top of a building to reach a certain height in a certain amount of time.

2. A good real world situation involving polynomials would be architecture. Factoring the polynomials can help to reduce the numbers you have to work with and make scaling the building a lot easier.

3. Say you own a painting company. You are asked to get a conference room painted in about 12 hours. Say Benjamin can do it in 12, Sally can do it in 10, and Alex can do it in 8 1/2. If you are good at factoring polynomials, you can figure out how long it should take them to get the room painted if they all work together. If you can't factor, they may take advantage of your math ignorance when you set them to work.

Factoring polynomials in 

real life   

Quadratics do play a role, for example, in area and construction problems.

Example: Suppose that you were told that a piece of land had a width that was 15 feet wider than its length, and that the area was 5800 square feet.

With that problem, you'll be ending up solving the equation  or further worked out,  which you would need to factor to get . 

Suppose that you have a bus, and you're renting it to organizations. Your bus can seat 80 people. You decide to charge the first person $30.00. If that person brings another person, you charge both of them $29.75 each. If there are three people, you charge $29.50 each. In other words, You charge EVERYBODY $0.25 less for every person who joins in. The thing is, there will come a point when you've got enough people to ride that you'll start losing profit if you add more people to the deal. With your starting price and discount price per additional person, will you: A) maximize your profit on the 80th person who rides? B) Be losing profit before you fill your bus, or C) would not yet reach your maximum profit on the 80th passenger?

So the total charge is dependent on how many people there are, how much you charge them, and what type of incentive you give depending on how many people there are. So, if there's one person, your total profit is $30.00. If there are two people, that's 2 people * ($30.00 - 0.25(1)). If there's 3 people, your total charge would be 3 people * ($30.00 - 0.25(2)).... Pretty soon, you'll see that your profit will be  or if simplified,
