Answer 4

@Brainybeauty

Answer 5

@Squirrels

Answer 6

The equation is\[3x ^{2} + 10x - 8\]

Answer 7

Ok, well that equation is written in quadratic form
\[ax^2+bx-=0\]

Answer 8

Are you familiar with the quadratic equation?

Answer 9

No :/

Answer 10

Ok this is the quadractic equation

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

Answer 11

Alright

Answer 12

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

Answer 13

\[ax^2+bx-c=0\]
\[3x^2+10x-8=0\]

Answer 14

Right

Answer 15

\[= \frac{ - 10 \pm \sqrt{100 - 4*3*(-8)} }{ 2*3 }\]

Answer 16

Now you must plug those numbers into the quadratic equation

Answer 17

Brainy, you should let him try it out, but yes that's correct.

Answer 18

yeah

Answer 19

I'm pretty sure you can figure out the rest @LearningIsAwesome
Just find both cases and those are your factors.

Answer 20

\[\frac{ -10 \pm \sqrt{196} }{ 6}\]

Answer 21

You want the rest of the answer? @LearningIsAwesome

Answer 22

@Brainybeauty do not give him the answer. Let him figure this out himself

Answer 23

oh okay

Answer 24

@LearningIsAwesome
If you want I can tell you how this equation was made

Answer 25

I kinda already told him, if you scroll up ^^^^ lol

Answer 26

Where do I go from there? I am like in the dark here

Answer 27

Yeah but I can tell the steps on how the quadratic equation came if he wants.

Answer 28

Ok let me tell you

Answer 29

\[= \frac{ -10 + 14 }{ 6 } or \frac{ -10 -14 }{ 6}\]

Answer 30

Okay... then what?

Answer 31

Yeah just a minute

Answer 32

\[= \frac{ 4 }{ 6 } ~ or ~ \frac{ -26 }{ 6 }\]

Answer 33

\[= 2/3 ~ or -13/3\]

Answer 34

Done @LearningIsAwesome

Answer 35

(3x - 8)(x + 1)

(3x - 1)(x + 8)

(3x - 4)(x + 2)

(3x - 2)(x + 4)

these are my options...

Answer 36

yeah so to find the factors, just subtract the factors from x

Answer 37

\[The~factors~are~ x-2/3 ~ and ~ x- (-13/3)\]

Answer 38

So you just multiple them and get
\[(x-2/3)(x+13/3)\]

Answer 39

Is that it?

Answer 40

@Brainybeauty, I told you not to give the answer -_-

Answer 41

Sorry @Squirrels
@LearningIsAwesome I went wrong somewhere correct it you will get the answer

Answer 42

I still just don't understand

Answer 43

Have to go write now. Sorry. And @LearningIsAwesome pay attention to our teachings instead of trying to get the answer. Bai bai for now

Answer 44

I AM!

Answer 45

But I don't get it!

Answer 46

:/...

Answer 47

@LearningIsAwesome If you want I can tell you how to solve this

Answer 48

Yes please T-T

Answer 49

Ok so you want to know how that equation came?

Answer 50

No...

Answer 51

so?

Answer 52

Can you tell me how to solve this? :/

Answer 53

ok

Answer 54

Yay!

Answer 55

:) There's not much to do
You just have to put the values of a, b and c in the quadratic equation and solve

Answer 56

so in the equation\[3x ^{2} + 10x - 8\]
a is 3
b is 10
and c is (-8)

Answer 57

Now put those values in the equation I told you above

Answer 58

got it? @LearningIsAwesome

Answer 59

I got it, I'm just gonna take a break my head's kinda spinning now and I'll just come back to it later ^^

Answer 60

Yeah!
Try it once you will get it!
And if you have any doubts just tell me I will try to help out! :)
It will be very easy once you understand it well :)

Answer 61

You can always medal me back brah :P ahhahaha

Answer 62

lol ok

Answer 63

Yes! 8 more til my title O.O

Answer 64

yeah! :)

Answer 65

cool
