Question

Helppp !!


Mr. Jones is asked to write two types of radical equations for the SAT Prep Course. The first solution to the radical equation must be extraneous. The second solution to the radical equation must be non-extraneous. Write one equation where the solution is extraneous. Then write a second equation where the solution is non-extraneous. Using complete sentences, explain each step when solving to justify your examples.

Answer 1

i believe albert einstein is dead if im not mistaken am i right

Answer 2

Unfortunately, you are correct ...

Answer 3

what math class are you in

Answer 4

Algebra 2

Answer 5

regular not AP not Honors

Answer 6

Algebra 2 lol ... Regular

Answer 7

oh man!!!!!! what's wrong with teachers now days they are killing students brain cells

Answer 8

too much excessive work

Answer 9

I have little to no brain cells left as a result of mathematics period lol

Answer 10

LOL well tells mr. Jones that ur contract for Algebra 2 expired LOL im a senior in hig school and i have college readiness Math preparing u for PERT

Answer 11

Lol i'm a senior also . Well , thanks for lightening the mood a bit but I really gotta get some help to get this done lol .

Answer 12

well as they always say!!! at first if you don't succeed try and try again!!!!! do i get a medal now? LOL

Answer 13

Haha you get a medal in my book . But I should probably safe it for someone who answers the question :p

Answer 14

nice talkin to u though I want to become a fan

Answer 15

Go for it haha

Answer 16

will do

Answer 17

\(\sqrt{x-4} = -3\)

Answer 18

@tkhunny i don't know what that is .. you gave me no explanation ..

Answer 19

I was just seeing if you were paying attention. What is the first request of the problem statement?

"The first solution to the radical equation must be extraneous."

That is a quick example of a radical equation with an extraneous solution.

Answer 20

Ohh ! Okay ! Clever lol .

Answer 21

@tkhunny ? You left me D:

Answer 22

.-.
I hate story math.

However, that aside, I must ask you to not explicitly state things like "automatic medal and fan" because that is not the website's purpose. The purpose of OpenStudy is for students to help each other on homework and strengthen their own learning abilities, as well as develop other core skills not commonly practiced in the classroom, NOT helping people for the benefit of fame or followers.
Therefore, please remove that part from your post, thanks.

I apologize if I sounded rude.

Answer 23

Lol yeah , that was kinda rude . I have seen that posted everywhere . Nothing gets said about it any other time . There is no rule stating that I cannot say that . Considering they are both FEATURES on this website . I was stating that so everyone was aware .

Answer 24

I don't really care about medals or fans. I'm hoping to see you learn the material you need.

Can you write a radical equation with both extraneous and non-extraneous solutions?

Answer 25

I would need to read up on what extraneous means , then I shall be able to answer that for you ! Give me a few moments to make sure I get it right :)

Answer 26

Well, I did apologize, and I just don't want you to get into trouble, so could you please take it off? :)

Answer 27

Also , since you're so kind . I will go ahead and award you that fan and medal :) @kittiwitti1 if it helps you sleep at night , sure . I should care about "getting in trouble" , but I don't .. but since you asked so nicely .. why not

Answer 28

Thanks (:
I'm sorry if I offended or annoyed you in any way. I didn't mean it like that :p

Answer 29

It's fine . Not a big deal really .

Answer 30

Okay well a radical equation with an extraneous solution could be: 1 = sqrt of x/3 - 2

Answer 31

@tkhunny

Answer 32

Sorry, the website is not working very well. I'm getting no notifications. I jsut have to check back when I can.

Is that this \(1 = \sqrt{x/3} - 2\)?

Answer 33

Omg same here ! And yes , that's correct haha .

Answer 34

Let's see... \(3 = \sqrt{x/3}\)

9 = x/3

x = 27

Checking

\(3 = \sqrt{27/3}\)??
\(3 = \sqrt{9}\)??
\(3 = 3\)??

That is a non-extraneous solution.

Answer 35

If you changed it to +2 you would have a bad one.

Answer 36

My work is completely different ...

Answer 37

Anything like this will do...

\(x = \sqrt{something}\) that leads to "Something" less than zero.

Answer 38

... or x < 0

Answer 39

Omg I think I get it now lol . No need to explain further :) I remember doing this now lol . Thank you so much though you really helped a lot !

Answer 40

Well, then you are awesome!!! Just a little shove in the right direction. Excellent work.

Answer 41

Thank you again you have no clue how much I appreciate your help ! I might need your help on one more question though .. Just let me answer this one real quick in my document
