Welcome to the general quadratic inequality machine!

Solve for x: x2 − 2x − 2 ≥ 0

all numbers
1 or 2 intervals

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.)
