Does it tell you how it wants it solved? Like a specific way?

- anonymous

the quadratic formula

- anonymous

do you know the formula by heart?

- anonymous

x=-b+/- sqrt b^2 -4(a)(c) all over 2(a)

- anonymous

yes

- anonymous

Ok so first you need to set your equation equal to zero

- anonymous

3x2+4x-2=0

- anonymous

good. Now do you know your values for a, b, and c?

- anonymous

Plug them into the equation?

- anonymous

Yes

- anonymous

(-3 \[\pm \sqrt{16 +24}) / 6\]

- anonymous

the two lines are in continuation

- anonymous

It should look like x=-4\[\pm \sqrt{4^2-4(3)(-2)}\] over 2(3)

- anonymous

So would it be -2 plus radical 10 all over 3|dw:1434907050388:dw|

- anonymous

How did you get that?

- anonymous

\[-4+\sqrt{}\]40

- anonymous

\[x=-4\pm \sqrt{16+24} \over 6\]

- anonymous

-4 plus or negative radical 40 all over 6

- anonymous

yes

- anonymous

Yes. then I simplifed

- anonymous

a=3; not 4

- anonymous

was I right?

- anonymous

I used a=3

- anonymous

What did you simplify to?

- anonymous

-2 plus/negative radical 10/3

- anonymous

|dw:1434907346795:dw|

- anonymous

How did you get there?

- anonymous

no uhmwhat... u wrote -4 in two consecutive comments

- anonymous

Where?

- anonymous

guys? Was I right??

- anonymous

let me check

- anonymous

your answer should be \[x=-4\pm2\sqrt{10} \over 6\]

- anonymous

That's not an answer choice

- anonymous

sorry... u r correct

- anonymous

When you take the sqrt of 40 you find two radicals that multiply to give you 40 (sqrt 4 and sqrt 10) the sqrt of 4 is 2 but the 2 is attached to the sqrt of 10 so you cannot do -4=/- 2

- anonymous

What are your answer choices

- anonymous

I pointed out something I thought was wrong

|dw:1434907656687:dw|

- anonymous

|dw:1434907713281:dw|

- anonymous

|dw:1434907746508:dw|

- anonymous

I think what the answers did was simplify further. It makes sense in theory of what they did. Personally I don't simplify further because it doesn't give you as accurate a graph but if that is what the test or questions want then yes you are correct
