SOLUTION
The given expression is,
[tex]x^2+13x+22[/tex]
The middle number is 13 and the last number is 22.
Factoring means we want something like:
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
1) Add together to get 13
2) Multiply together to get 22
Can you think of the two numbers?
Try 2 and 11:
1) 2+11 = 13
2) 2*11 = 22
Fill in the blanks in
(x+_)(x+_)
with 2 and 11 to get...
Therefore,
[tex](x+2)(x+11)[/tex]
Hence, the correct choice is A.
The answer is,
[tex](x+2)(x+11)[/tex]
