To factor the expression ( n^2 + 13n + 22 ), you need to find two numbers that multiply to ( 22 ) and add up to ( 13 ). These numbers are ( 11 ) and ( 2 ). Then, you can rewrite the expression as:

( n^2 + 11n + 2n + 22 )

Now, you can factor by grouping:

( (n^2 + 11n) + (2n + 22) )

( n(n + 11) + 2(n + 11) )

( (n + 11)(n + 2) )

So, the factored form of ( n^2 + 13n + 22 ) is ( (n + 11)(n + 2) ).
