Best Answer

Divide them by prime numbers until all the factors are prime.

3 is already prime.

The prime factorization of 6 is 2 x 3.

The prime factorization of 12 is 2 x 2 x 3.

If you're looking for the GCF, select the common factors.

The GCF is 3.

If you're looking for the LCM, combine the factors, eliminating duplicates.

2 x 2 x 3 = 12, the LCM.

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
