00:0-1	at first glance , this problem may look extremely difficult
00:05	because it's set up as a special kind of try
00:08	no meal that can be factored as the product of
00:10	two by no meals and there's a coefficient on your
00:13	X squared term . And look at your constant term
00:17	that you're going to have to factor negative 24 .
00:20	Think of all of the different possible factors of negative
00:23	24 you'll see you'll have a bunch of different pairs
00:27	of dino meals to choose from in the problems in
00:30	this section . However , you can make your life
00:33	a lot easier by understanding one simple idea . Before
00:38	you do anything else in this problem , look to
00:41	see if the greatest common factor exists in this original
00:45	try no meal . Notice that for every term In
00:50	your original problem , there is a factor of three
00:54	. That means that a three can factor out of
00:57	the tri no meal and you're left with X squared
01:02	plus two x minus eight . Inside the parentheses ,
01:09	look at how much easier to deal with this .
01:11	Try no meal is than your original . Try no
01:14	meal . Our next step will be to factor what's
01:18	in here and all we have to do is split
01:20	up into two by no meals . Looking for the
01:23	factors of -8 that add to positive too . Since
01:29	those factors are positive for and -2 . Our final
01:34	answer is three times X plus four times X minus
01:42	two and you're done .
