C. Third degree polynomial with three terms.
Terms are, by definition, the number of nonzero coefficients for powers of x. In this case, there are 3 nonzero coefficients (3 terms) because . For example,
has one term, but
has 0 terms.
The degree of a polynomial is the highest power involved in the expression. In this case, it's , so the degree is 3.

In both cases,
(as a consequence of the interesecting secant-tangent theorem)
So we have
10.
(omit the negative solution because that would make at least one of AB or AD have negative length)
11.
(again, omit the solutions that would give a negative length for either AB or AD)
