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 the gcf of 40 and 60 and 80?

The gcf is the greatest common factor. A way of finding the gcf of three numbers is to find the gcf of the first two and then finding the gcf of that number and the third number. Because of the unique prime factorization theorem, the greatest common factor will be a product of some of the prime factors in either number. The prime factorization of 40 is 2^3 * 5 and the prime factorization of 60 is 2^2 * 3 * 5, so the gcf is going to be what is in both, or, in this case, 2^2 * 5. Th prime factorization of 80 is 2^4 * 5 and so gcf of all three numbers is 2^2 * 5, or 20.

What is the greatest common factor of 32 8 and 40?

Method of prime factorization is one of the best method to find out greatest common factor.Prime factorization of 32 = 2x2x2x2x2Prime factorization of 8 = 2x2x2Prime factorization of 40 = 2x2x2x52x2x2 is a factor of each number. Also, it is the greatest number which divides 32, 8 and 40. So, gcf is 8.See the related links below to know more about prime factorization.
