Hey!

Let's simplify this...    

x² + 6x + 8       --------> Now, we need to find two numbers that multiply to 8 and                                        also add up to 6
factors of 8 
1
2        ---->
4        ---->   These two multiply to 8 and add up to 6 
8

Let's solve this now!

x² + 6x + 8
(x + 4)(x + 2)         ----> If you want to check your answer just FOIL them
Your x-intercepts will be -4 and -2

Hope this helps! :D
