Question

3x^2 + 8x + 2 = 0

Answer 1

Yo!

Answer 2

I'll have it solved here in just a sec

Answer 3

thats because you are pro! and i've been trying to remember the formula you gave me.

Answer 4

\[ac = (\frac{b}{2}+d)(\frac{b}{2}-d)\]

Answer 5

Solve for d

Answer 6

You can also just use the quadratic formula

Answer 7

Whats the formula for that?

Answer 8

\[x = \frac{-b \pm \sqrt{b^2-4ac}}{2a} \]

Answer 9

Just input a = 3, b = 8, c = 2 into the equation and solve for x

Answer 10

How do i do a and c? do i combine them together? or..?

Answer 11

yes, when you see ac it means the values of a and c are multiplied

Answer 12

right now i have .. \[x=-8 \pm \sqrt{40} \] / 6

Answer 13

is that right?

Answer 14

looks right...hold on

Answer 15

okay..

Answer 16

Yes, it is correct

Answer 17

You just have to simplify it further

Answer 18

\[x = \frac{-8 \pm \sqrt{40}}{6} = \frac{-4 \pm \sqrt{10}}{3}\]

Answer 19

There ya go

Answer 20

Good job on solving it yourself

Answer 21

Thanks to you! Thank you!(:

Answer 22

But yet. Im still confused on what is the answer o.o

Answer 23

That IS the answer

Answer 24

I just simplified it further for you

Answer 25

All you were supposed to do is solve for x. You did that

Answer 26

And x =..? o.o

Answer 27

Look up....

Answer 28

\[x = \frac{-8 \pm \sqrt{40}}{6} = \frac{-4 \pm \sqrt{10}}{3} \]

Answer 29

notice how it says x = .....

Answer 30

that is the form you would write it in having used the quadratic formula

Answer 31

And how would it be the other way? And Oh i get it now.. ~for the quadratic formula

Answer 32

It would be the same way the other way....but like this:

\[(x + \frac{4 + \sqrt{10}}{3})(x + \frac{4 -\sqrt{10}}{3}) \]

Answer 33

You just have to work with these a little more to understand

Answer 34

oh okay o.o

Answer 35

oh okay o.o
