## anonymous one year ago Choose the polynomial that is written in standard form. 2x3y2 + 4x4y + 8x7 −3x4y2 + 4x4y5 + 10x2 6xy2 + 4x3y8 + 9x2 −2x5y3 + 4x2y2 + x2

1. triciaal

standard form write "highest exponent" first

2. anonymous

oh @triciaal

3. anonymous

so c ?

4. triciaal

no - for the variables -- let me double check when 2 variables

5. anonymous

ok sure. sorry im kinda lost

6. triciaal

I thought it was d need verification

7. triciaal

@dan815

8. anonymous

oh great thanks! Can u plz help me with one more?

Find the quotient

14. anonymous

10x2 + 3x − 4 −40x3 − 12x2 − 4 −10x2 + 3x − 4 10x2 − 3x + 4

15. UsukiDoll

hey.. don't force drag me into these problems. I'm taking a break! @triciaal

16. triciaal

the quotient is what you get when you divide

17. anonymous

oh i got u

18. triciaal

@UsukiDoll I am so very sorry to ask for verification. I will not bother you anymore. sorry.

19. triciaal

@xnick2000 did I miss the problem?

20. anonymous

im not sure what the answer for the quotien one is

21. anonymous

is it b? thats what i got when i did the work

22. triciaal

did not see the question

23. anonymous

oh sorry let me post it again

24. anonymous
25. anonymous

10x2 + 3x − 4 −40x3 − 12x2 − 4 −10x2 + 3x − 4 10x2 − 3x + 4

26. triciaal

27. triciaal

just type the problem in the Draw

28. UsukiDoll

29. anonymous

oh ok

30. anonymous

-40x^3 - 12^2x + 16x over -4x

31. UsukiDoll

split it up into 3 division parts for that question|dw:1435292455155:dw|

32. triciaal

|dw:1435296002545:dw|

33. anonymous

i see so then i just divide them

34. UsukiDoll

don't forget the exponent rule for subtraction/divison

35. UsukiDoll

$\frac{n^a}{n^b} =n^{a-b}$

36. UsukiDoll

let n = variable a and b = numbers

37. anonymous

no a sorry

38. anonymous

a?

39. UsukiDoll

I said let n = variable and let a,b = numbers geez

40. UsukiDoll

let n = x a = 3, b = 1 . now use the exponent rule to solve for the variable part of the problem

41. anonymous

Im saying the ANSWER IS A?

42. UsukiDoll

show work first.

43. anonymous

I did it on paper, i divided all of them but i have a doubt between a or d

44. UsukiDoll

like what is -40/-4 -12/-4 16/-4 solve the number portions

45. anonymous

1. 10 2. 3 3 . -4

46. UsukiDoll

ok now solve the exponent portions

47. UsukiDoll

you need one of the exponent rules $\frac{n^a}{n^b} =n^{a-b}$ for the first portion let n = x, a = 3 and b = 1

48. anonymous

10x^2 + 3x - 4

49. UsukiDoll

$\frac{x^3}{x^1} =x^{3-1}$ which is?

50. anonymous

idk

51. UsukiDoll

subtract 3-1

52. anonymous

i think either a or d

53. anonymous

2

54. UsukiDoll

ok so now we have x^2

55. UsukiDoll

|dw:1435293160747:dw|

56. anonymous

:) thank you!

57. UsukiDoll

now use the exponent law again .. this time for $\frac{x^2}{x^1} =x^{2-1}$

58. UsukiDoll

I want to make sure you understand what's going on .

59. UsukiDoll

so what's 2-1 for that second x ? We're going to have just an x right?

60. anonymous

i did a long time ago i just had a doubt!!

61. UsukiDoll

k... so you used to know but forgot.. that happens to everyone. you just have to re-practice that material. I have tons to re-practice x(

62. UsukiDoll

|dw:1435293312680:dw|

63. UsukiDoll

it was the first choice.

64. UsukiDoll

... sorry something is stuck. I don't have anything more about this problem because we have completed the process and got the answer
