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 is 8487 divisibility rule?

The number must be divisible by 9, 23 and 41, so all three of the following conditions must be met.Divisibility by 9 requires you to check the sum of the digits is divisible by 9.Divisibility by 23 requires you to add 7 times the last digit to the rest. The answer must be divisible by 23 directly.For divisibility by 41, subtract 4 times the last digit from the rest. The answer must be divisible by 23 directly.In each case, the additions or subtractions can be repeated so as to make the answer easier to test for divisibility.


What is the divisibility rule for 400?

for any composite number ... check only the highest power of prime factors divisibility .... i guess that will do the work for example ... 400 = 2^4 * 5^2 so you need to check the divisibility by 25 as well as 16 hope this will meet your need
