[00:00:07] Welcome to Tutor.com !
[00:00:10] My name is Nisha!
[00:00:17] Have you used the Tutor classroom before?

[00:00:32] Great, let's get started! :-)
[00:00:39] Can you write your equation on the board please
[00:01:21] Thanks!
[00:01:24] So what can we do first?

Guest (Customer)
[00:01:36] factor

Nisha S (Tutor)
[00:02:28] Good! And what can we do first to factor?

Guest (Customer)
[00:02:39] find the greatest common factor

Nisha S (Tutor)
[00:03:06] Show me on the board please
[00:04:54] Great job! And what can we do next?

Guest (Customer)
[00:05:20] that is where im stuck at

Nisha S (Tutor)
[00:05:51] So we want to set each of the parenthesis equal to 0 and solve
[00:07:32] Can you solve these please
[00:08:46] Excellent work! Any questions about this?

Guest (Customer)
[00:09:15] what do you do about the 2?

Nisha S (Tutor)
[00:09:48] All the factors need to be set equal to 0, since 2 cannot be set to equal to 0 you disregard it
[00:10:26] (in other words, it would be the same as if we divided each of the original numbers by 2 instead of pulling it out, that would be the same)
[00:11:24] Any other questions about this/

Guest (Customer)
[00:11:46] no
