Welcome to the general quadratic inequality machine!
Solve for x: x2 − 2 > 0
Note: due to the limitations of computer keyboards, you likely don't have an ∞ key, so just write “inf” or the like; if you write anything that I can't parse as a number then I'll assume you mean ±∞.
Please write your answer in interval notation.
If you want to write two intervals, put a ‘u’ between them. (That means they're both solutions.)
