I need to simplify it? By adding those terms together?

#32 Re: Help Me ! » A Multiplying and Dividing Polynomials Problem » 2012-09-06 05:38:12

I have a very slight idea of how to do these.. Barely. I'm very bad with these type of problems.
Could I have the work for this problem?

Thanks bobbym, that's what I needed. Could you show me the work or that?

These are some more problems of the same type that I got wrong in my newest lesson! I'll need the answers and your work for it.

#41 Re: Help Me ! » Multiplying and Dividing Polynomials » 2012-08-22 08:18:25

I don't have time to write the new answers.
I've submitted them to my teacher though and they're correct!

I'm about to go make a new post!

Hey guys, I need some more help.
These are the problems I got wrong and I don't have much time to work on the revised versions because so much is happening in my life right now. We're moving, parents are splitting up and we're not even staying at our house right now. A whole ton of stuff is going on right now and honestly it's scary. So, I'm short on time and I need help..

The problems I got wrong:

1.

3.

4.

5.

6.

7.

8.

THANKS GUYS!

I pretty much lost what you guys were talking about..

So, I'm just going to post a revised version of #17..

17.


Answer:

I really hope that's correct..
If it isn't would someone just tell me the correct answer?

#45 Re: Help Me ! » Adding and Subtracting Polynomials » 2012-08-15 11:12:20

17) should be

Except there should be a minus sign between the two 2's..

18) should be

19) should be

#46 Re: Help Me ! » Adding and Subtracting Polynomials » 2012-08-15 05:33:52

Thanks noelevens! smile

Okay, Bob Bundy, I've redone the first 2 I got wrong. Hopefully, this is better.

14. (7x + 4) – (2x + 9) 
5x – 5

16. (x3 + 2x^2 + 5x) – (3x^2 – x – 7)
x3 – x2 + 6x + 7

17. (5x^4 – 2x^2) – (3x – 2x^2 - 4x^3 + 6x^4)
-2x^4 - x3 + 4x^2 + 3x

18. (-x^2 + 4x - 3) + (x2 – 2x + 6)
2x^2 + 2x + 3

19. (-4x^3 – x2 + 8) + (5x^2 - x – 12)
-4x^3 + 4x^2 – x + 4

#47 Re: Help Me ! » Adding and Subtracting Polynomials » 2012-08-14 04:19:32

Okay, I tried those 10 problems noelevens!

1)  7-(-2) = 9

2)  -8-3=  5

3)  -9+5= -4

4)  -3*(-4)= 12

5)  -5-(-7)= 2

6)  7-(-3)=  10         

7)  -5+(-9)= -14

8)  -18/3= -6

9)  -2-7= -9         

10)  (-2)-(-9)= 7

I'm pretty sure these are all correct.. I think my problem is with the rearranging the numbers so you can simplify. I don't know how to do that very well.

#48 Re: Help Me ! » Adding and Subtracting Polynomials » 2012-08-13 07:19:30

Okay, thanks guys! I think I'm understanding this..

13. (8x^2 + 2x + 1) + (x^2 – 4x + 7)
The answer should be 9x2 – 2x + 8?

14. (7x + 4) – (2x + 9) 
The answer should be 5x – 13? Or is it 9x + 13 ?

15. (4x^3 + 6x^2 – 8x) – (x3 - 2x^2 + 12x)
The answer should be 5x^6 + 4x^2 – 4x ?

16. (x3 + 2x^2 + 5x) – (3x^2 – x – 7)
The answer should be -2x^3 + x2 - 2x ?

17. (5x^4 – 2x^2) – (3x – 2x^2 - 4x^3 + 6x^4)
The answer should be 9x^4 - x3 + 4x^2 + 3x?

18. (-x^2 + 4x - 3) + (x2 – 2x + 6)
The answer should be ?

19. (-4x3 – x2 + 8) + (5x2 - x – 12)
The answer should be 9x3 – x - 4?

20. (-5x2 - 5x + 3) – (6x2 – x)
The answer should be -11x2 - 4x + 3?

#49 Re: Help Me ! » Exponents and Scientific Notation » 2012-08-13 04:31:16

Thanks Bob Bundy!
As for #2, I figured that out myself. It was super simple and I had already gotten the correct answer it was just written wrong.
Oh and bobbym, you were correct. I'll make sure I do that in the future.

It looks like zee f and I are taking the same course! I had all those same questions!

Well, in the other lesson I'm working, I got 4 out of 20 wrong.

I don't understand them and am unable to work it out.

The problems;
simplify the following exponential expressions:
2. (x-3)5

9. Divide the following numbers using scientific notation: (4 x 102)/(1 x 103)

19. Estimate the amount of juice in a typical orange juice carton in liters.
(That's a strange question, huh?)

20. Estimate the weight of a small can of soup in grams.
(Again, strange question if you ask me.)

Anyway, I need the correct answer and the steps you used so I can (hopefully) understand it myself! big_smile

Thanks!
