Add more explanation

The sets with x^2 contain negative numbers, so your min/inf is not correct here. This detail should be mentioned in the solution, maybe hint. It would also be nice to give a one-sentence description of the last set as it's not obvious what is happening here.

Clearly was a typo =p

Okay yea so I'm not sure really what to do here. What is the best way to give the description of this solution? Maybe the answer and a small one 'sentence' explanation?

Agree, it should be the answer plus a small one-sentence explanation. This could happen in the hint or solution.
