Where are my Mathletes?
I've never done a partial fraction this long

Don't be a bitch and crank that thing out yourself.

>>5676296
You don't need to actually solve it, just say the form. You'll get a summand from each factor of the denominator.

>> No.5676323 [DELETED]

It's pretty much in the image
The first and the last parentheses are divisible (obviously), so they are like:
<span class="math">{A \over {x^n+\alpha}^2} + {B \over {x^n+\alpha}}<span class="math">
The two on the middle are like
{Cx+D} \over {x^2+\beta x+\delta}[/spoiler][/spoiler]

>> No.5676339

I seriously don't know how to do this

it looks to me like I'm going all the way up to H

Am I supposed to multiply them out?
The denominator I mean?
Then divide the polynomials?

Alright, so I multiplied out the denominator

looks like I'm supposed to divide now

>> No.5676420

>>5676409
That's a good first step.

Next, notice that 7 and 5 appear most often as coefficients, so you should evaluate the polynomials in the numerator and denominator for the value x = 7/5. Once, you have worked out that fraction, post it in this thread, and we will tell you what to do next.

not sure what you meant by that
so I tried to divide them

this look like I'm getting somewhere?
I think I'm going to try and factor out the denominator

>> No.5676500

>>5676481
You need to find a different area of study.

You already had it factored, and were told not to multiply it out. You tried anyway, and got the wrong answer. The denom has degree 10, not 8.

Now you want to factor it out? Go to bed!

Good.
Then do so.

Pornographic images and racism are not necessary for you to 'contribute'.

>> No.5678169

>>5676296
Please look on wikipedia, the trick will get obvious. One thing that took me a few minutes to notice is that in the numerator, they try a polynomial of degree n-1, where n is the smallest degree occuring in the factors in the denumerator. Also, just list all combinations of factors in the denumerator.

Look and it'll become clear, hopefully.

>What's pornographic about that image?
It is an image of a naked person. How do you think that it is not pornographic?

I am neither angry nor unloved, and I do not need any attention.
If you wish to contribute, then do.
But I am finished talking to you.

search up the term pornography please. you get to see more pornography in an MTV musical video of an african-american interpret .
In my picture: you cant see boobs/asshole/pussy. There's no humping involved or anything else. Is just a girl sitting with her private areas covered. Hell I see more boobs on news on national TV. (without being marked age inappropriate)
