We determine whether the trinomial is a square. Since only y 2 is a square, we do not have a trinomial square. Can the trinomial be factored by trial and error? A key to the answer is that x is only in the term 7xy . The polynomial might be in a form like 1 y 2 y , but there would be no x in the middle term. Thus, 2 7xy y 2 cannot be factored. C) Have we factored completely? |
