Hi;
I have two very loud air conditioners from the two zombies who live next door to me and require air conditioning when the outside temperature is 51 F. I guess they have to keep their skin from rotting off their already ugly faces...
I needed to know the intensity of the noise they were producing. I got it from these two sites

If you use their calculator you will see the book answer is correct.
They appear to be using this formula:

Looks like he tried 1 x 6 and 2 x 3 for factors of 6 and then did the same thing for 15.
Can you copy the problem so that I can see what you are dealing with?
Hi;
You mean you want to factor a polynomial? Can you provide an example of what you mean?
Hi;
Can you provide the settings to generate the 5 examples?
I think tonyjaa is quoting these definitions rather than showing they are understood.
Is that true tonyjaa? Here is the simplest, bare bones answer that I know.
I mean , a number can be factored into a product of its prime .
And what exactly is a prime number ?
Its a number that can only be evenly divided by that number itself and one ?
There are only two types of whole numbers, composite numbers and prime numbers.
Composite numbers have more factors than 1 and the number. For instance:
45 is composite because it can be factored like this 3 x 3 x 5 = 45. Notice it can be factored into smaller numbers which are prime. 100 is composite because it can be factored into 2 x 2 x 5 x 5 = 100. Again. it can factored into smaller numbers that are prime. On the other hand, 103 can only be factored into 1 x 103 = 103. Notice it can only be factored into 1 and itself. 103 is a prime number.
Do not be worried if there is much about primes you do not understand. You can say that the human race has spent thousands of years on the many questions still left unanswered about them.
Everything else you seem to have a good grasp of unless I missed something .
Yes, that is what gets it done.
In math does everything start with whole numbers ?
Maybe, but you can a long way without ever knowing much about the whole numbers.
12 / 5 is the same as 12 ÷ 5.
in other words 12 is the dividend and 5 is the divisor ... right ?
The first thing you are going to have to overcome to learn math is to overcome the jargon. To start, put things in terms of words that you understand, even if they are not mathematically the best. For instance:
Numerator and denominator: The numerator is the stuff that is on the top of the fraction and the denominator is the stuff on the bottom. Learn to understand all concepts in simple terms first. Later on, you will refine your thinking.
