The link for the key is below.  Please be aware of a couple of things:
1)  In the last section, every problem that says "real" should be replaced with "rational."  Also:  2 imaginary solutions is equivalent to no solution
2)  On the real test tomorrow, there will be some irrational solutions in that last section.
3)  In the problems where you clear fractions, expect at least one problem where there will be two answers (solving a 2nd degree equation).
