Lorie H (Tutor)

[00:00:08] Welcome to Tutor.com .
My name is Lorie.
How are you?

Guest (Customer)

[00:00:35] great thanks

Lorie H (Tutor)

[00:01:05] I think I was just working with you.
Are you supposed to use the quadratic equation to solve this?

Guest (Customer)

[00:01:14] yes! haha

Lorie H (Tutor)

[00:01:42] Okay, let me put up what we had...the equation and quadratic formula

Guest (Customer)

[00:01:46] ok

Lorie H (Tutor)

[00:02:42] First of all, let's identify what a, by and c are... do you know what a is?

Guest (Customer)

[00:02:57] 5

Lorie H (Tutor)

[00:03:13] Right!

[00:03:16] What is b?

Guest (Customer)

[00:03:49] -3

Lorie H (Tutor)

[00:04:07] And, finally, what is c?

Guest (Customer)

[00:04:43] -15

Lorie H (Tutor)

[00:05:14] Great!

[00:05:33] So, we need to put each of those numbers into our quadratic equation where it asks for them.

[00:05:37] Can you do that?

Guest (Customer)

[00:07:11] sure

[00:07:32] i actually have an answer

[00:07:42] well... i did almost all the
proble

Lorie H (Tutor)

[00:07:48] Okay...what is your answer?

[00:07:59] That's okay!

Guest (Customer)

[00:07:59] then i got stuck at 3+/-^-291

Lorie H (Tutor)

[00:08:26] Okay...there is a small problem there...let's look at it.

Guest (Customer)

[00:09:16] ok

Lorie H (Tutor)

[00:09:21] That is how you started, right?

Guest (Customer)

[00:09:32] yes

Lorie H (Tutor)

[00:09:54] Now, here is where the signs get a bit tricky.

[00:10:13] 4 times 5 times -15 is -300...right?

[00:10:51] That means we are actually not going to have -291 under the square root sign.

[00:10:56] What will we have instead?

Guest (Customer)

[00:11:22] ohh i messed up with the -15

[00:11:41] so 309

Lorie H (Tutor)

[00:11:47] Right!

Guest (Customer)

[00:12:12] ok

Lorie H (Tutor)

[00:12:22] So, that is what you needed to have your answer correct.

[00:12:41] Any questions over this problem?

Guest (Customer)

[00:13:11] nopee

[00:13:17] do u know the final answer

Lorie H (Tutor)

[00:13:43] Well, it depends if you can leave the final answer in this form, or if you need decimals.

[00:13:55] Were there directions on that?

Guest (Customer)

[00:14:12] no

[00:14:16] just round to hundreth

Lorie H (Tutor)

[00:14:46] Okay, so you need to do decimals (that is what round to the hundreth means)...round to two decimal places.

[00:15:00] Do you have a calculator to do this?
You will have two answers.

Guest (Customer)

[00:15:22] yess

[00:15:37] i got 2.06&-1.46

Lorie H (Tutor)

[00:15:47] You are correct!

[00:15:49] Great job!

Guest (Customer)

[00:15:56] yay

[00:15:57] one more?
