X^2 + 5x + 13 pls help

Not factorable

Step-by-step explanation:

We are given a polynomial and are asked to solve or factor it I am assuming.

To solve this, there is a certain rule I like to follow, which is for b (in this case 5), you have to find two numbers that multiply to it, and for c (in this case 13), you have to find two numbers that add to it.

Since no two numbers multiply to 5 and add to 13, therefore this polynomial is not factorable.
