Answer 2

@mondona

Answer 3

i give medals

Answer 4

@phi

Answer 5

someone...

Answer 6

ill help if your still here.

Answer 7

its actually really simple.
distribute, and combine like terms.

Answer 8

im here

Answer 9

2(x - 12)^2 + 6
2(x-12)(x-12)+6

Answer 10

distribute from there

Answer 11

is that the standard?

Answer 12

no not yet.

Answer 13

How do i distribute?

Answer 14

... the distribute property. Like you would do any other day.
lets first distribute out the (x-12)s...which is
(x-12)*(x-12)
Can you do that? Heres a hint on starting...
(x*x)+(x*-12)+ ...distribute from the parenthesis (x-12)(x-12) from there..i started it for u

Answer 15

Does this step make sense?

Answer 16

2x^2-48x+294 ?

Answer 17

(x-12)(x-12)
(x*x)+(x*-12)+ (-12*x)+ (-12*-12)
x^2 -12x-12x+144
x^2+144 is what I got when I distributed them.

Answer 18

Would it be cheating if i checked it on mathway?

Answer 19

no wait! i subtracted it wrong... x^2-24x+144
.... is this a quiz? or quick check?
Idk... it depends on the teacher.

Answer 20

its part of an assessment

Answer 21

the scientific calculators that they give us (for connections) will actually solve these problems for us...
It could not mean anything, just as long as it is only checking your answer. you should at least try it on your own-but i dont know what online school you're doing so im probably not the one to ask.

Answer 22

dang. I'm on FLVS if that helps.

Answer 23

no idea. lol.
im all the way in WI sir. xD
just try it. Trust me, its not even that hard-this is the easy stuff.

Answer 24

Im reallhy bad at algebra 2

Answer 25

really*

Answer 26

Also the quadratic form is based off my birthday so could it be a possibility that it doesn't work?

Answer 27

2(x^2-24x+144)+6=y
that is perfectly fine. I sucked too...but it all started making sense when I started asking why we were using all of these methods. what the math really all meant and how it applied to the real world...instead of just how it applied to the grade.
Im helping you. And gosh darn it, I will do all in my power to help you understand this! Don't give up. Calculators are only for checking. :)

Answer 28

Question-Do you know how to distribute, or is it confusing?

Answer 29

confusing

Answer 30

everything is confusing most of the time

Answer 31

No, whoever you are. I don't think your cursed. lol. xD
Okay...hmm... Do you have a skype, or would u prefer I break it down via here?
You shall not be confused anymore!

Answer 32

no skype :/

Answer 33

I checked mathway, 2(x−12) (x−12)+6 rewritten in standard form is 2x2−48x+294. I WAS RIGHT :D

Answer 34

what happened to that...

Answer 35

Ok then. You obviously know how to distribute if that is the case.....erm its just being weird. thats just open study...in a lil bit itll become readable.

Answer 36

yea lol

Answer 37

i have one more that i have no clue what it even means

Answer 38

okay. shoot.

Answer 39

Using complete sentences, explain how to find the average rate of change for f(x) from x = 4 to x = 7.

Answer 40

Erm. Haven't seen this in my lessons...
Have you heard of Khan Academy?
https://www.khanacademy.org/math/algebra/linear-equations-and-inequalitie/average-rate-of-change/v/average-rate-of-change-example-1

Answer 41

As for making complete sentences...its math. they're not asking for a paragraph. just say the answers in complete sentences by saying numbers numbers numbers is the average rate of change for f(x) from x=4 to x=7.

Answer 42

k. i have a graph for it that you can look at

Answer 43

ok. Ehh. I doubt I'd be able to help much with this.

Answer 44

ill attempt tho.

Answer 45

watch the video its pretty straight forward though

Answer 46

f(x) = 2(x - 12)^2 + 6

Answer 47

google that and itll come up

Answer 48

you mean the link that I gave you, you want me to watch?

Answer 49

okay ill google it...

Answer 50

yes

Answer 51

ok...the formula to find slope m, is y2-y1/x2-x1

how to find the average rate of change for f(x) from x = 4 to x = 7.
look for x=4 to x=7 on the graph...and...
i think thats the same as saying x is greater than or equal to 4 or less than or equal to 7...check it out on the graph....between those x's.

Answer 52

I think that you should see the y values when x=7 and x=4...when looking on that graph...then figure out the slope using the formula i just gave ya.

Answer 53

are you following or did I loose you?

Answer 54

but then again...i have do no idea if this is right lol.

Answer 55

im lost in this terrible labyrinth called math

Answer 56

Give me the link to your textbook. tell me the chapter, and lesson this crazy stuff occurs in.

Answer 57

Or screen shot it and save it to a doc

Answer 58

I'm sorry, but is the rage of change 4<x<7?

Answer 59

the link may not work so here it is. http://learn.flvs.net/educator/student/frame_toolbar.cgi?jjoyner25*karma911*mpos=1&spos=0&option=hidemenu&slt=oQG2gxi8LvrkQ*3941*http://learn.flvs.net/webdav/educator_algebraII_v13/index.htm

Answer 60

eh nah. it doesn't....but is he rate of change 4<=x<=7?

Answer 61

those equation signs means or equal to.

Answer 62

k. im about to just go with that. can you explain how you got this

Answer 63

I took the numbers....x=7 and x=4...assuming i had to go between them and assumed that the relative thingy is in between those x values...
sorry im absolutely NO HELP.

Answer 64

yu helped at first but this is just insane

Answer 65

yerp. lets just call it a day and blaim the government.

Answer 66

this is why im gonna work at a grocery store

Answer 67

THANKS OBAMA!

Answer 68

Oh don't say that. come'on now. Don't give up. I totally beieve you can do it...just look over your textbook and watch video tutorials to explain it like a teacher would...
and Omygosh lol. Yes! Curses to the government. *raising a communist flag* (too far;))

Answer 69

dang commie

Answer 70

does it matter if i give you a medal or whatever

Answer 71

nah. i didn't earn it lol.
that would be cheating. But remember my tag, as usually math is my thing. I may or may not be able to help you. I've never seen this stuff before tho, and im also in alg 2.

Answer 72

k thank you, you did help

Answer 73

k may the force be with you, stranger! live long and prosper on your journey through his third dimension!

Answer 74

k then lol
