A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

What number between 20 and 30 has a sum of all its proper factors equal to twice the number itself?

There aren't any numbers like that. You might be thinking of 28, which has a sum of all its factors equal to twice itself, making it a perfect number. Proper factors are a different set.

How can you prove that a perfect number can never be a prime number?

In a perfect number, the sum of all the factors (including the number itself) is twice the number. E.g., the sum of the factors of 6 is 1 + 2 + 3 + 6 = 12 (equal to 2 x 6). Every prime number has two factors: 1, and itself. So, the sum of the factors is only one more than the prime number itself; for any number greater than 1, this can't be twice the number. For example, the prime number 7 has the factors 1 and 7, which add up to 8.


How can multiples be shown as factors?

Can you explain why 10 has an even number of factors but 16 has an odd number of factors?

Because 16 is a square number and you wouldn't list the 4 twice.


Why does a square number always have an odd number of factors?

One of the factor pairs for a square number will be the same number twice. When you list the factors, you only need to write that number once. That will leave you with an odd number of factors.


What two prime numbers equal 44?

To find the primes that equal a number, start with any factor pair of the number and keep factoring the composite factors until all factors are prime. 44 2 x 22 2 x 2 x 11 = 44 The two prime numbers that equal 44 are 2 (twice) and 11.


Why number 33 is perfect?

It is not. A perfect number is defined as a number that is equal to twice the sum of all of its factors (or equal to all of its factors, smaller than the number itself). Perfect numbers include 6 (factors 1, 2, 3, 6) and 28 (factors 1, 2, 4, 7, 14, 28). It is not known whether there are odd perfect numbers. - Unless somebody is using a different definition of "perfect" in this case; but when you talk about a "perfect number", the above definition is commonly used.

Which number is greater then 25 and has the most factors?

There is no such number with "most factors"; if you have a number with a certain number of factors, you can always multiply it by 2, or by 3, etc., to get another number that has even more factors.


Draw algorithm and flowchart to check a number is perfct or not?

1. List all factors of number (including 1 and the number, list each factor only once even if it goes in multiple times) 2. Add up all the factors 3. If the sum is equal to twice the original number, then the original number is perfect, if not, it is not perfect.


Why does number 25 have a odd number of factors?

Because it's a square number. All perfect squares have an odd number of factors because they have one factor pair that is the same number twice (the square root) and when the factors are listed, the number is listed once.
