Question

my answer: 2x2 - 4x - 3 - 4x - 3/13 ??????

question: Let f(x) = 8x3 - 22x2 - 4 and g(x) = 4x - 3. Find f(x)/g(x)

Answer 1

am i right or am i right

Answer 2

lol.

Answer 3

@zepdrix, is she right? I think she may not be.

Answer 4

FML

Answer 5

well u have to try and simplify first so how did u factor the top?

Answer 6

f(x)**

Answer 7

So we can work this one out using Polynomial Long Division.

I worked it out and I came up with,
\[\large \frac{f(x)}{g(x)}=2x^2-4x-3, \qquad \text{with a Remainder of -13}\]

Which we can write like this.
\[\large \frac{f(x)}{g(x)}=2x^2-4x-3+\color{royalblue}{\frac{-13}{4x-3}}\]

It looks like you had everything correct except for that last little part! :)
Just remember to put your Remainder (left overs) on top of the initial Divisor that you had (4x-3 in this case).
