If I have to solve x^2 < 2, I get
or What now?Offline
Its
Thats the solution. When you solve for x in an inequality generally, the solution is a range of values rather than a single value.

In this case, you can also neaten it up a bit by saying
.Why did the vector cross the road?
It wanted to be normal.

Thanks... so the sign is flipped for the negative root so that x remains within the boundaries
