Who wants to do my HW?

Alright I need to do my HW. But I am leaving somewhere right now so I won't have time to do it. Here is it.

Factor each of the following expressions either by inspection or by using the grouping method discussed in your text. If a greatest common factor can be removed first, factor it out. I DID #1 already xD.

1) 2x^2 + 7x +3
A) (2x + 1) (x+3)

2) 3y^2 + 13y +4

3) 3a^2 + 10a + 4

4) 7x^2 + 8r +1

5) 4r^2 + r -3

6) 3p^2 + 2p - 8

7) 15m^2 + m - 2

8) 6x^2 + x -1

9) 8m^2 - 10m - 3

10) 2a^2 - 17a + 30

11) 5a^2 - 6 -7

12) 11s + 12s^2 - 5

13) 3r^2 + r - 10

14) 4y^2 + 69y = 17

15) 4t^2 - 5t - 6

16) 8k^2 = 2k - 15

17) 8x^2 - 14x + 3

18) 15p^2 - p - 6

19) 6q^2 + 23q + 21

20) 6x^2 - x - 12

21) 2 + 7b + 6b^2


I am expcepted to get this done by tomorrow in the morning. So please help me with it thanks.

Please help!!
 
Look in the back of the book for some answers and copy off someone for the rest or hire a tutor to do it for you.
 
[quote name='BoxShot' post='2475864' date='Dec 22 2009, 05:52 AM']It isn't hard at all. :P I'll do some since I'm bored.[/quote]

You know he's just using you right? Isn't the purpose of homework to learn how to do it from your mistakes?

Jakob, Do your own dam homework.
 
I know. Boredom is boredom. I personally don't care if he fails at doing this on a test. :P I'm only going to do like what 5.

Why is there 2 different variables in the questions?

Why is 2 and 3 the same but one different variable?
 
I'd help, but I'm not this far into math barely in geometry. Sorry I'm in 9th grade right now. =p Is this algebra 1
Never learned this or forgot whats it called??
 
[quote name='Rock Raiyu' post='2475881' date='Dec 21 2009, 09:59 PM']You have got to be shitting me....is this Algebra I or II?[/quote]

You honestly have to ask? It's obviously Algebra I.

If he had Algebra II he'd be asking us what an imaginary number is.

I love those things. I have the nerve to ask jakob95 what 7i^2 is!

But seriously, go do your homework. This is not difficult.
 
1) 2x^2 + 7x +3
A) (2x + 1) (x+3)

2) 3y^2 + 13y +4
A) (3y + 1) (y + 4)

3) 3a^2 + 13y + 4
A) (3y + 1) (y + 4) <- change your variable depending on the one used in the real question

4) 7x^2 + 8r +1
A) (7x + 1) (x + 1) <- see #3a comment

5) 4r^2 + r -3
A) (4r - 3) (r + 1)

Jakob you screwed up copying your own questions. I did 5 and now I'm done.

Do it Raiyu do it! He would also ask about cramer's law. :P Which I found annoying to remember since I rarely had to use it.
 
[quote name='jakob95' post='2475853' date='Dec 21 2009, 10:49 PM']5) 4r^2 + r -3

6) 3p^2 + 2p - 8
= (3p-4)(p+2)

7) 15m^2 + m - 2
= (5m+2)(3m-1)

8) 6x^2 + x -1
= (3x-1)(2x+1)

9) 8m^2 - 10m - 3
= (4m-1)(2m+3)

10) 2a^2 - 17a + 30
= (2a-5)(a-6)

11) 5a^2 - 6 -7
I DON'T THINK THIS SHIT'S FACTORABLE.

12) 11s + 12s^2 - 5
= 12s^2 + 11s - 5
= (3s-1)(4s+5)

13) 3r^2 + r - 10
= (3r-5)(r+2)

14) 4y^2 + 69y = 17
= 4y^2 + 69y - 17
...I GOT STUCK.

15) 4t^2 - 5t - 6
= (4t+3)(t-2)

16) 8k^2 = 2k - 15
= -(8k^2 - 2k + 15)
..I GOT STUCK.

17) 8x^2 - 14x + 3
= (4x-1)(2x-3)

18) 15p^2 - p - 6
= (5p+3)(3p-2)

19) 6q^2 + 23q + 21
= (3q+7)(2q+3)

20) 6x^2 - x - 12
= (2x-3)(3x+4)

21) 2 + 7b + 6b^2
= 6b^2 + 7b + 2
= (3b+1)(b+2)


I am expcepted to get this done by tomorrow in the morning. So please help me with it thanks.[/quote]


You guys are fucking slow.
 
I fixed #3 sorry. I wrote it wrong... Ima copy the answers later ima go to sleep.
