Answer:
(n + 4)(n + 5)
Explanation:
to factor n² + 9n + 20, we need to find 2 numbers that when multiplied together equal 20 and when added together equal 9
these two numbers are 4 and 5 so the factorization looks like this:
(n + 4)(n + 5) < you can FOIL this out to check if the solution is correct, and you would get: n² + 9n + 20
