Question

Which polynomial represents the sum below?

(-2x^3 + 4x^2 + 6) + (2x^2 + 6x + 3)

A. -x^6 + 6x^2 + 12x + 9
B. -2x^3 + 6x^2 + 6x + 9
C. -2x^5 + 10x^2 + 6x + 9
D. -2x^3 + 6x + 9

Answer 1

Your answer should be B if you put all the common parts together you will find you can not simplify the equation any longer

Answer 2

thank you so much

Answer 3

No problem do you understand it?

Answer 4

yes i do now thank u

Answer 5

Which polynomial represents the sum below?

(2x^6 + 3x^2 + 9) + (3x^2 + x + 8)
this is the answer i got 5x^8 + 3x^4 + x + 17 did i do it right

Answer 6

mmbuckaroos did i do this right ?

Answer 7

Ha ha let me check sorry I was working on something else...

Answer 8

ok no problem

Answer 9

No that's not right....Here I will go through the problem step by step

Answer 10

(2x^6 + 3x^2 + 9) + (3x^2 + x + 8)
ok between both the sides what do you see in common?

Answer 11

3x^2

Answer 12

Right... so because there is nothing in common with 2x^6 I leave that then I would add the two common parts together so add 3x^2+3x^2 together and you should get 6x^2

Answer 13

Then there are no other x's so you leave the x alone. then add the 9&8 together and you should get 17.

Answer 14

ok yea now im getting it

Answer 15

Your final answer should be 2x^6+6x^2+x+17

Answer 16

Does that make sense i didn't do the best job explaining it sorry

Answer 17

yes it does now that u explained ill try another one and get back to u

Answer 18

Alright sounds like a plan Stan! Lol I'd trade that math for mine any day! lol

Answer 19

lol :)

Answer 20

6x^7+9x^3-x+9
+ 2x^7+7x^6+6
this is the answer i got is it right 8x^7+7x^6+9x^3-x+15

Answer 21

how is this one mmbuckaroos

Answer 22

ok so what is your original equation again sorry is it:
6x^7+9x^3-x+9+2x^7+7x^6+6

Answer 23

yes and the answer i got is 8x^7+7x^6+9x^3-x+15
is it right

Answer 24

Yes sir! you got it good job!

Answer 25

well thank you im proud lol :)

Answer 26

Ha ha good you should be!

Answer 27

Which polynomial represents the sum below?

(4x^2 + 3x + 4) + (-3x^6 - 4x^5 - 2x^2 + 5x)
ok the answer i got is -x6 - 4x5 + 2x2 + 8x + 4

Answer 28

close look over it again.. I think you meant -3x^6

Answer 29

oh ok sorry yea i looked it over

Answer 30

Other than that you've got this down!

Answer 31

Good job!

Answer 32

Which polynomial represents the sum below?

(18x^2 - 18) + (-13x^2 - 13x + 13)
ok well the answer i got is 5x2 - 13x - 5

Answer 33

5x^2 - 13x - 5

Answer 34

i ment that

Answer 35

Yeppers! You're on a role!

Answer 36

wow thx u oh yea:)

Answer 37

Ha ha no problem!

Answer 38

7x^8 +5x^5 - x+8
+ 5X^10 +9X+8
the answer i got is 12x16 + 4x4 + 7x + 16

Answer 39

No...make sure you have the correct original problem

Answer 40

If you do your highest power should be 5x^10 and there is nothing in common with that

Answer 41

5x10 + 7x8 + 5x5 + 8x + 16 is this the answer

Answer 42

yep!

Answer 43

sweet :)

Answer 44

Good job!

Answer 45

(x^6 + x ) + (8x^6 + 4)
the answer i got for this one it 9x^6+5

Answer 46

I have to go get a horse trimmed, but if you have anymore questions I'll be back to answer them in a while

Answer 47

ok thank you very much for your help :)

Answer 48

alright sorry about that... Your last problem would be 9x^6 +x+4

Answer 49

im here

Answer 50

do oyu see where you made your mistake on that last one?

Answer 51

*you

Answer 52

yea

Answer 53

cool beans!

Answer 54

2x^5 -3x^3 + x^2 +4
+ -3x^5 -2x^4 +x^3 +4x

the answer i got is -1x^5 + 5x^6 + 2x^5 8x+-1

Answer 55

what do you think buck

Answer 56

close
-x^5-2x^4-2x^3+x^2+4x+4

Answer 57

(5x4 - 3x2 - 2x) + (2x4 + 2x3 + 2x2 + x + 1)
i really cant get this one

Answer 58

(5x^4 - 3x^2 - 2x) + (2x^4 + 2x^3 + 2x^2 + x + 1)

Answer 59

this is the right one

Answer 60

ok give me a sec

Answer 61

ok thank you

Answer 62

what is your answer

Answer 63

i couldnt get the answer for this one

Answer 64

ok...
what do you see in common

Answer 65

3x^2 2x^3

Answer 66

mm not quite...
ok so what's the highest power and is there anything similar to it

Answer 67

4 is the highest power

Answer 68

so what is in common with 5x^4

Answer 69

2x^4

Answer 70

right so add those together to get 7x^4 then do you see anything in common with 2x^3?

Answer 71

yea 3x^2

Answer 72

No because they have a different power... only alike powers can be put together.. Comprende?

Answer 73

sorry getting tired lol

Answer 74

2x^2

Answer 75

so 2x^3 should be by itself... ha ha it's ok and 2x^2 add that to -3x^2 because they share the same power.. are you following ?

Answer 76

yup so what next

Answer 77

you should get -x^2... Next, you have the x's with out powers in common (x & -2x) so you should put those together to get -x.

Answer 78

Then the 1 is all by it's lonesome self.
Your answer should be:
7x^4+2x^3-x^2-x+1

Answer 79

thank you so much for all your help im leaveing im am tired

Answer 80

ha ha no problem anytime get some rest math wiz!
