b.it's first term is a perfect square
c. it is a polynomial with three terms
d. it's middle term is always negative

A square of a binomial (perfect square), means that the two binomial terms are the same. Therefore, both terms will include either a double positive (which would result in a positive answer), or a double negative, (which, by the law of multiplying double negatives, would result in a positive answer).

Therefore, D will be the correct "incorrect" answer.
