The correct factorization is (p + 16)(p + 2).
You can find this by looking for factors of the final number that add up to the middle number. Factors of the final number are listed below:
1 * 32
-1 * -32
2 * 16
-2 * -16
4 * 8
-4 * -8
Now you select the one that adds to 18, which would be the highlighted 2 and 16. Now we use these in parenthesis with a p + in the front of it.
(p + 2)(p + 16)
This will be the correct factored form.
