aum · Answer

All you have to do is divide (x^4 - x^3 - 24) by (x + 2)

aum · Answer

If you are going to do synthetic division, remember to put in the coefficient for the missing terms:  1x^4 - 1x^3 + 0x^2 + 0x - 24   divided  by (x + 2)

D again looks closest to what i am thinking of...

aum · Answer

Try again.  remember you are dividing by (x + 2).  So in synthetic division you should divide by -2.

okay...i did that part wrong.

specek18 · Answer

i feel like a and e are wrong....also d is. so it's gotta be b, or c...right?

looking again kinda thinking a....

aum · Answer

1x^4 - 1x^3 + 0x^2 + 0x - 24 divided by (x + 2):

-2      1   -1   0     0   -24
               -2   6  -12    24
        ------------------
          1   -3   6  -12      0

x^2 - 3x + 6x - 12

it is b.....

specek18 · Answer

ugh. i'm sorry i'm terrible at math

aum · Answer

oops, the last line should be: x^3 - 3x^2 + 6x - 12

specek18 · Answer

yeah i figured because everything else matched:)

aum · Answer

It is b.
