Base 8.

You can confirm by plugging 3 into the equation. You will get -2. So obviously, your base is 2 off to the left. I was of course, doing it in base 10 so 2 to the left of 10 is 8.

However, I never did a problem like this so to not end up like an idiot, I did confirm it using my calculator that can calculate in different bases.

base 8

well i have this but now i dont know what to do :c

x2 − 11x + 22 = (x − 3) (x − 6)

x2 − (b+1)x + (2b+2) = (x − 3) (x − 6)
