This is how you divide
OpenStudy (anonymous):
long division or synthetic division
OpenStudy (anonymous):
That isn't one of the answers. Either one, it doesn't specify.
OpenStudy (anonymous):
i was suggesting to you use either one of them.
you asked how to divide it and i suggested 2 methods.
sam (.sam.):
Of course you'll have to rearrange it in the form
\[(Quotient)+\frac{Remainder}{Divisor}\]

you need to add the following to the top quotient
\[\frac{ -37 }{ x-2 }\]
OpenStudy (anonymous):
I don't get it. Why do I need to do that?
OpenStudy (anonymous):
cuz its the remainder of course
OpenStudy (anonymous):
Sam got it ;)
OpenStudy (anonymous):
@.Sam. Can you explain it to me?

he did in the pic + he later told u how to rearrange it
OpenStudy (anonymous):
But it didn't match up. \[-3x ^{2}+2x+24 \]
\[-3x ^{2}-10x-16 R -29\]
\[-3x ^{2}-10x-16 \]
\[-3^{2}+2x+24 R35 \]
Are the choices for the answers
OpenStudy (anonymous):
idk then.
his answer is right
OpenStudy (anonymous):
@precal Do you know how to do this?
OpenStudy (anonymous):
unless you wrote the question wrong?

Oh.. Yeah I did. -3x^3-4x^2+4x+3 by x-2
OpenStudy (anonymous):
.___.
WOW!
OpenStudy (anonymous):
I'm really sorry.
OpenStudy (anonymous):
\[-3x^3-4x^2+4x+3 / x-2?\]
OpenStudy (anonymous):
