Hello there!
Simply find a common term that they all have!
So they can all be divided by 6, right? So let's take a 6 out.
6 (x^2-8x-20)
Now factor the terms in the parenthesis!
6 (x-10) (x-2)
^ This is NOT your answer!!
Tip: When looking at (x^2-8x-20), look at the middle term. (-8x). Since it's negative, either (x-10) or (x-2) can be negative.
Which one is negative? Well, is the 8 positive or negative? Since the 8 is negative, the parenthesis bigger number (x-10) will be negative!
So it'll be:
6 (x-10) (x+2)
ALWAYS double check your answer by foiling! :)
Hope this helped!
