To solve this, we have to know what it'll look like: (x + )(x + ) We also know 2 numbers will multiply to get 12, but add to get 8. Let's go through the factors of 12 to see what makes 8. 1 + 12 = 13 2 + 6 = 8 3 + 4 = 7 And we found it! 2 and 6 multiply to get 12, but add to get 8. So, plug them in. (x + 2)(x + 6) Just to double check, let's multiply it out. x^2 + 2x + 6x + 12 x^2 + 8x + 12 Perfect! Hope this helps!
