Question

Just for verification, can you please check my answer?

Question: 3(x+2) = 6
------
2(x+1)

my answer:
6(x^2+3x+1)
Work:
expanded first after multiplying both sides with 2(x+1).==> 6x^2+18+6==> took 6 out. to get final answer. Am i correct

Answer 1

What are your instructions?

Answer 2

Solve for x... shoot that means its incomplete.

Answer 3

Yep

Answer 4

im stuck :( whats the next step?
i cant think of any factors of 6x^2+18x+6... ah am i not suppose to factor, and use quadratic formula?

Answer 5

Hang on, what is the equation you just posted equal to?

Answer 6

my previous post is the multiplication of both sides with 2x+2

Answer 7

You have 6x^2+18x+6=0 right now, right?

Answer 8

like (3x+6)(2x+2) = 6
=>6x^2+18+12 = 6 ==> 6x^2+18+6

Answer 9

yes = 0

Answer 10

Perfect, so then you can factor out the 6 like you did before and use the quadratic formula on what's in the parentheses

Answer 11

ok one sec.

Answer 12

ok so it would be
___ ___
3 ±√-1 and 3 ±√-1
------ -------
2 2

Answer 13

just the quadratic formula answers

Answer 14

*First one = + not ±
*Second one = - not ±

Answer 15

Can you show me how you set up the quadratic formula because I got \[(-3\pm \sqrt{5})/2\] for the answer

Answer 16

umm ok -b ± √-b - 4ac
---------------
2a

so -3±√3-4(1*1) / 2(1)

* hey im sorry but can you help me in an hour? im at work and i over procrastinated and i need to finish my work, but ill be back online within an hour or hour and a half.

Answer 17

I gotta go soon, but FYI your formula's wrong: it's supposed to be b^2-4ac under the radical

Answer 18

Oh im sorry that was a typo...in both.

Answer 19

Ah i see, i did this within my previous answer too.

Answer 20

Does that solve the problem?

Answer 21

yes, but what would my final answer look like?

6 ((-3±√-5)/2) ?

Answer 22

No, because the 6 we factored out earlier doesn't affect the final answer because if we divided both sides by 6 before using the quadratic formula, we'd get x^2+3x+2=0 since 0/6=0

Answer 23

I hope that made some sense

Answer 24

So, your final answer would be \[(-3\pm \sqrt{-5})/2\]

Answer 25

Because the 6 canceled earlier

Answer 26

hmm ok i think i understand. because we divided 6, theres no need for its return. so i would just write x = (-3±√-5)/2

Answer 27

Yes! :)

Answer 28

Unless your book/teacher want you to write the two answers separately

Answer 29

In which case it would be \[x=(-3+ \sqrt{-5})/2\] and \[x=(-3-\sqrt{-5})/2\]

Answer 30

Any more questions?

Answer 31

Umm that's all for now, i should do my work now. But thank you very much :)
I'll most likely post more questions within an hour or so to check my work so make sure i don't make mistakes like this again :p

Answer 32

Thanks again, bye

Answer 33

No prob. Bye
