Let f(x) = 8x^3 - 22x^2 - 4 and g(x) = 4x - 3. Find f(x)/g(x)

Divide the two functions
rebeccaxhawaii (rebeccaxhawaii):
yeah obviously but i need help
OpenStudy (astrophysics):
Have you tried factoring
rebeccaxhawaii (rebeccaxhawaii):
well i got 2x^2-4x=13/4x-3 but thats not one of my choices
OpenStudy (astrophysics):
Let me ask you something, are all the signs correct

There's not much to simplify here, check if you posted correctly
rebeccaxhawaii (rebeccaxhawaii):
i mean i got 2x^2-4x+13/4x-3
OpenStudy (astrophysics):
\[\frac{ 2(4x^3-11x^2-2) }{ 4x-3 }\]
OpenStudy (astrophysics):
Not much you can do
rebeccaxhawaii (rebeccaxhawaii):
no\[4x-3\sqrt{8x ^{3}-22x ^{2}-4}\]

Whattt you didn't even say that..
rebeccaxhawaii (rebeccaxhawaii):
sorry i inserted it wrong the first time
OpenStudy (astrophysics):
Wait so is \[f(x) = \sqrt{8x^3-22x^2-4}\] and \[g(x) = 4x-3\]
rebeccaxhawaii (rebeccaxhawaii):
no that is a division sign
OpenStudy (astrophysics):
\[\frac{ 4x-3 }{ 8x^3-22x^2-4 }\]

rebeccaxhawaii (rebeccaxhawaii):
yes
OpenStudy (astrophysics):
Still not much you can do
rebeccaxhawaii (rebeccaxhawaii):
yes but there is a solution
rebeccaxhawaii (rebeccaxhawaii):
no there is not
OpenStudy (michele_laino):
I think that we can apply the procedure of long division

rebeccaxhawaii (rebeccaxhawaii):
well there is an answer i just messed up in some part and thats why im here
rebeccaxhawaii (rebeccaxhawaii):
yes this is what i need help with the lesson is titled polynomial long division
OpenStudy (michele_laino):
using the procedure of long division I got a different result
OpenStudy (michele_laino):
here is what I got:
\[\huge 2{x^2} - 4x - 3 - \frac{{13}}{{4x - 3}}\]
is it the right result?
rebeccaxhawaii (rebeccaxhawaii):
YES THAT IS CORRECT thanks so much

see guys there is an answer theres no "well theres not much you can do"
OpenStudy (michele_laino):
please try to do such division on your own, since the direct answer is against the Code of Conduct
rebeccaxhawaii (rebeccaxhawaii):
k well thanks anyway
OpenStudy (michele_laino):
