Determine the base of the number, explain me the process ;_;!!!!!

x2 − 11x + 22 = 0

x=3 x=6

There are literally thousands of primary school tutors out there, anon. Out of every place, you chose here, and worst of all didn't even read the rules.

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)
