Question

Hey im on Polynomials and Factoring Unit Test can someone help me please .

Answer 1

Unfortunately, we are not allowed to give our answer on test.

Answer 2

But I can try to help xP

Answer 3

What's your problem? c:

Answer 4

Welcome to openstudy! :-)

I'm sorry but we're not allowed to help on tests/quizzes/exams/assessments here :/
that would be considered cheating :(

However feel free to come back for homework help.

Answer 5

i just need help with the basics of how to do polynomials
and factoring it

Answer 6

once i figure that out then ill be okay doing it myself

Answer 7

Do you have a problem that ISN'T on the test that we can show you how to do them? c:

Answer 8

yes . would you like to message me privately i dont want it to get to messy
on here

Answer 9

and no it wont be the actual test question will be different numbers

Answer 10

we can do it on here! There is a "Draw" button on the bottom, if you can see it c:

Answer 11

okay yeah i see it
alright one second let me double look at my test and make sure im not giving u the same prob

Answer 12

i know these questions are prob going to be like realy u cant do them ... i just dont understand alg at all so please bear with me

Answer 13

sorry had to do something real quick

Answer 14

Awe man, I have to go. Ugggghhhh I wish I could stay to help, but it's late already for me

Answer 15

I'm really sorry, maybe you can tag someone who can help show you how to do polynomials.

Answer 16

REally dont know anyone on here

Answer 17

Let me see

Answer 18

@AlexandervonHumboldt2

Answer 19

thanks

Answer 20

It's not a test question Shurik, she just needs to be shown how to solve a polynomial :P

Answer 21

:( ima busy :"(

Answer 22

AWe man

Answer 23

yeah maybe i should of stated whwat i need help for lol

Answer 24

Maybe you can do another post c:

Answer 25

I don't know anyone else who is good with polynomials :p

Answer 26

dang ... Do you think alex does .. i know they are busy but maybe they know someone

Answer 27

Well, let me see real quick before I leave c:

Answer 28

thanks for helping me .

Answer 29

@Needhelpstudying are you good with Polynomials and Factoring

Answer 30

Kinda, but I'm busy with my own homework lol @MaNdEe . Sorry.

Answer 31

Thats okay @Needhelpstudying

Answer 32

@MaNdEe Is it urgent?

Answer 33

I sent you a message, mandee :p

Answer 34

Thanks hun ! i just seen it

Answer 35

Hold on @MaNdEe , give me 5-7 minutes, and I can probably get you someone who can help

Answer 36

awe Bye ;~:

Answer 37

Figure this stuff out yet? :)

Answer 38

lol no .. not really .. i just dont understand it ..

Answer 39

What are you trying to do?
I still don't see a problem posted 0_o

Answer 40

i know i was busy for a second and Chan had to go so i was over looking my test to make sure that i dont have the same numbers

Answer 41

what i need to know for the first few things is degree for monomials

so ill post samples ...

Answer 42

3x^10

Answer 43

it would be 10 right ?

Answer 44

If you like,
you can post the actual question and I'll just come up with examples.
At least when it comes to factoring you might want me to do that.
Cause coming up with your own examples would be difficult.

Answer 45

Degree is the "power" on x, so yes, 10 :)

Answer 46

okay now what if it is a single number as of 5 im guessing it would be to the first power right?

Answer 47

So that's where things get a little tricky.
Recall that anything to the 0 power is simply 1.
\(\large\rm 3^0=1\)
\(\large\rm a^0=1\)

So when you're given something like \(\large\rm 5\),
you're trying to think of a power being applied to this invisible x that we don't see.

Answer 48

so the power would be 0

Answer 49

\[\large\rm 5\quad=5\cdot1\quad=5\cdot x^0\]

Answer 50

Good :) zero power on x.
It's a little difficult to see it at first because it's hidden.
Think of it like "how many x's are multiplying this 5?"
None.

Answer 51

right .. as long as i get help with this i can understand it but my teachers are just so...evil .. dont want ot help no one

Answer 52

Ooo that's no fun :x

Answer 53

okay so now for the next set its finding sum or difference .

Umm lets say ...

4x^10-9x^10

Answer 54

Lemme do another example :)
Just in case you're a sneaky cheater buhaha.

5x^12 - 7x^12

So don't get too confused by x^12,
it's just a "thing".
Let's call it an apple.

So your problem is really
5apples - 7apples

Answer 55

no not cheating promise

Answer 56

so -3

Answer 57

sorry -2

Answer 58

@MaNdEe I think @zepdrix has got this. :)

'Night everyone :)

Answer 59

Thanks

Answer 60

Well it's more than just -2.
It's -2apples, right?

Answer 61

yeah 5-7 would make it a neg

Answer 62

or do u have to multiply .. ?

Answer 63

The point I was trying to make is that you still have the "things" attached to that number.
It's 5apples take away 7apples.
So you end up with -2apples.

Or in other words, -2x^12

Answer 64

oh okay my bad

Answer 65

so because its a power u have to multiply bt -2?

Answer 66

0_o

Answer 67

im sorry ... i think i confused myself...

Answer 68

If I have 10oranges and I take away 4oranges
I'm left with 6oranges, yes?

I'm not just left with the number 6,
I'm left with 6`oranges`.

So if instead I have 10x^12 and I take away 4x^12,
I'm left with 6x^12

Not just 6, that wouldn't make sense.

Answer 69

Okay got you . I confused myself for a second im sorry .

Answer 70

:3

Answer 71

okay so ill give you the tesst question and you can change it so you dont think im cheating .

Answer 72

\[7t^5-10t^5\]

Answer 73

wait that will be ....-3t^5??

Answer 74

Hmm that seems like a good answer ;) maybe

Answer 75

i think it is .. im going with that awnser..

Answer 76

okay so now this one is write the polynomial in standard form . Then name the polynomial based on its degree and numbers of terms

Answer 77

the question is \[2-5x^3+6x\]

Answer 78

So when we're given something like this:
\(\large\rm 7x^2-12x^4+5-x\)

This is already very very close to standard form.
All they want us to do is put them in the correct "order".
They want the powers on x to start largest from the left,
and decrease towards the right.

Answer 79

Clearly the x^4 is the LARGEST power of x, ya?
But you've got to be careful! See the subtraction in front of it?
That is part of the number.

Answer 80

soo puttting that together it would be -12^4

Answer 81

-12^4+7x^2-x+5

Answer 82

right?

Answer 83

That first term should be -12x^4,
but yes good job c:

Answer 84

yeah forgot the x .. so what do you do from there?

Answer 85

Oh right right, we have to "classify" the polynomial now.

Answer 86

so because its 3 x's its a tri?

Answer 87

A `monomial` is a single term, example: 3x
A `binomial` is a string of two terms, example: 5x + 4

Answer 88

The counting includes the one without an x,
because (remember) we determined that he is still an x, he just has a 0 power.

Answer 89

So I guess we want to use the prefix "quadri" or something,
quadrinomial

Answer 90

And we dealt with degree earlier, yes?
Highest power of x in our example?

Answer 91

yeah,,

Answer 92

so can i ask u something

Answer 93

what is a fourth degree trinomial ?

Answer 94

fourth degree means the highest exponent is a 4,
trinomial means it is a string of three terms being added/subtracted.
Example of a fourth degree trinomial:
\(\large\rm 12x^4-x-7\)

Just so it's clear, the example I was doing before was a fourth degree quadrinomial
\(\large\rm -12x^4+7x^2-x+5\)

Answer 95

Its a quartic

Answer 96

The name is

Answer 97

I think quartic means 5 doesn't it? :o
