Answer:
1) D. 
2) E. The coefficient of
is -16.
Step-by-step explanation:
1) A polynomial is an algebraic expression of the form
, where
is the grade of the polynomial. In this case, the only equation that satisfies this definition is:

Correct answer: D
2) Let
, we proceed to expand the expression by algebraic means:


We see that coefficients for
and
are -16 and 0, respectively. Hence, the incorrect answer is E.
