Best ResponseYou've already chosen the best response.1You are trying to factor a trinomial of the form: \(x^2 + ax + b\) For this type of factoring, you need to find two numbers whose product is b and whose sum is a. In this case, you need two numbers whose product is 36 and whose sum is 20. If two such numbers do not exist, then the trinomial is not factorable, so it's prime.

Best ResponseYou've already chosen the best response.1Factors of 36 Sum of the factors 1, 36 35 36, 1 35 18, 2 16 2, 18 16 12, 3 9 3, 12 9 9, 4 5 4, 9 5 6, 6 0 As you can see, there are no two factors of 36 which have a sum of 20. That means this trinomial is not factorable. it is prime.
