Yes, it can. This happens when all of the observations are equal. This can also happen when some values are negative and some are positive (assuming that the variable under consideration can assume negative values).

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
