Factor x^2 - 23x + 22.
a. (x - 1) (x - 22)
b. (x + 1) (x - 23)
c. cannot be factored
d. (x - 2) (x - 11)

Your answer is A. (x - 1)(x - 22)
This is because you need factors of 22 that make 23, and these are 22 and 1, and the fact that the end number is positive means that the signs must be the same, and the middle sign is negative so both signs must be negative.

I hope this helps!
