How do we factor trinomials ?

 Factor x² + 14x + 24

So ,the best way to solve these problems is doing the diamond method. In other words the big X
The 24 on the bottom and on top of the X is 14. You need to find to numbers that multiply to 24 and add to 14. In this case its -> 2 and 12. 
Final answer should be (x+2)(x+12)
