[00:00:06] Hello.
[00:00:09] Thanks for using tutor.com
[00:00:18] I see that we have an algebra problem.
[00:01:09] I'm not sure where the second set of parentheses are on this.

Guest (Customer)
[00:01:45] ( is supposed to be (
[00:01:53] 9 is (

Rick G (Tutor)
[00:02:01] Gotcha.

Guest (Customer)
[00:02:25] no nine just 3
[00:02:30] 3x

Rick G (Tutor)
[00:02:49] Like that?
[00:02:59] Ohhh.

Guest (Customer)
[00:03:01] no nine at all
[00:03:05] yes

Rick G (Tutor)
[00:03:19] Ok. cool. Does that all look right?

Guest (Customer)
[00:03:32] yes

Rick G (Tutor)
[00:03:41] Ok. What can we do first?

Guest (Customer)
[00:04:03] factor?

Rick G (Tutor)
[00:04:29] We won't need to factor this. Do we need the parentheses at all?

Guest (Customer)
[00:04:52] I dont know

Rick G (Tutor)
[00:05:11] We can get rid of them because both of our groups of terms have positives before them.
[00:06:02] Does that make sense?

Guest (Customer)
[00:06:13] yes

Rick G (Tutor)
[00:06:29] Ok. Now, all we have to do it combine like terms if we can.
[00:06:34] What can we combine?

Guest (Customer)
[00:06:47] the x cubed terms

Rick G (Tutor)
[00:06:57] Good! What does that become?

Guest (Customer)
[00:07:12] 8x^3

Rick G (Tutor)
[00:07:25] Nice. What else?

Guest (Customer)
[00:07:41] -10x and -7x
[00:07:45] -17x

Rick G (Tutor)
[00:08:07] Good.
[00:08:09] Anything else?

Guest (Customer)
[00:08:12] no

Rick G (Tutor)
[00:08:27] How about the 12 and 3?

Guest (Customer)
[00:09:52] I have a factoring problem if you would like to help

Rick G (Tutor)
[00:10:05] Alright. Let's do it.

Guest (Customer)
[00:10:40] 3x^2+30x+63

Rick G (Tutor)
[00:11:05] Ok.
[00:11:17] What can we do first?

Guest (Customer)
[00:11:42] start with 3x in two seperate parenteses

Rick G (Tutor)
[00:12:00] Hold on. We can take a GCF out of the whole group first.
[00:12:33] Does that make sense?

Guest (Customer)
[00:12:35] yes

Rick G (Tutor)
[00:12:50] Ok. Cool. Now let's factor the inside.

Guest (Customer)
[00:12:56] ok

Rick G (Tutor)
[00:13:11] We need factors of a times c that add to b.
[00:13:57] Got it?

Rick G (Tutor)
[00:14:16] And we're done!
