You said that you had to solve the problem, and then find any extra solutions, correct? If so, how would you solve the problem? Once you solve the problem, you find that the answer is b.

first thing is first, the problem already says: \[\sqrt{a}=-2\] right? If so, then you know that if you so then, you would know that if you multiply by -2 on both sides, i believe.
