The correct solution set is not included among the other choices.

The correct solution set is not included among the other choices.

Explanation:

FOIL:

These are our possible solutions. However, we need to test them.

:

The equation becomes . This is true, so  is a solution.

:

However, negative numbers do not have logarithms, so this equation is meaningless.  is not a solution, and  is the one and only solution. Since this is not one of our choices, the correct response is "The correct solution set is not included among the other choices."
