Carolyn K (Tutor)
[00:00:07] Welcome to Tutor.com ! How are you today?

Shivam (Customer)
[00:00:16] m good.. how are you?
[00:00:26] I am stuck on this problem...

Carolyn K (Tutor)
[00:00:31] I'm doing great! Thanks :) What are the directions for this question?

Shivam (Customer)
[00:00:43] it says solve

Carolyn K (Tutor)
[00:01:03] We can simplify, but to solve we'd need an equation
[00:01:08] to solve for m
[00:02:07] Do you want me to assist you to simplify this expression?

Shivam (Customer)
[00:03:16] sorry it says that simplify and assume that no denominator is 0\

Carolyn K (Tutor)
[00:03:27] Okay :) Thanks
[00:03:38] We can use special factoring patterns
[00:03:44] to help us get started on this
[00:03:52] I have written two that we will need to use
[00:03:59] the difference of two squares
[00:04:07] and the difference of two cubes
[00:04:21] Are you familiar with these factoring patterns?

Shivam (Customer)
[00:04:23] can I try solving this now?
[00:04:25] yeah

Carolyn K (Tutor)
[00:04:35] Great! Sounds good!
[00:05:29] Are you familiar with how to use the whiteboard?
[00:05:38] If you would like to show your steps
[00:05:43] I can check them for you :)

Shivam (Customer)
[00:05:51] nope... first time

Carolyn K (Tutor)
[00:06:08] Okay :) There is a toolbar below the screen
[00:06:16] there is a pencil tool
[00:06:22] that will allow you to write on the board
[00:06:26] Do you see it?
[00:06:36] This is how I wrote what is in blue

Shivam (Customer)
[00:06:43] yeah I do but is happening

Carolyn K (Tutor)
[00:07:01] If you click on it
[00:07:09] you will be able to use your mouse
[00:07:17] to write with the pencil

Shivam (Customer)
[00:07:54] give me a sec

Carolyn K (Tutor)
[00:08:21] Okay :) Let' me know if you have any questions about using the whiteboard
[00:08:25] I'll try to help :)

Shivam (Customer)
[00:10:09] can u solve it as m not able to write?

Carolyn K (Tutor)
[00:10:37] I can work through it with you

Shivam (Customer)
[00:10:43] sure

Carolyn K (Tutor)
[00:10:46] You can also type here
[00:10:59] and I can check your steps

Shivam (Customer)
[00:11:05] ohkay

Carolyn K (Tutor)
[00:11:13] What do you think we can replace the numerator with ?

Shivam (Customer)
[00:12:06] (m-2)(m2+2m+64)
[00:12:28] (m-2)(m+2)

Carolyn K (Tutor)
[00:12:53] You are very very close
[00:12:58] this third term
[00:13:03] b^2

Shivam (Customer)
[00:13:08] 4

Carolyn K (Tutor)
[00:13:18] instead of 64, Right! 4
[00:13:46] Awesome :) Do you think that you know what we can do next?

Shivam (Customer)
[00:13:54] ohkay it
[00:14:14] yeah you cross out the (m-2) from both the denominator and numerator

Carolyn K (Tutor)
[00:14:36] Exactly! As factors these will cancel
[00:14:47] The result is your simplified form

Shivam (Customer)
[00:14:52] yeah and that's the ans
[00:14:55] thankyou

Carolyn K (Tutor)
[00:15:13] You're welcome :D
