Can you [email protected] my third attachment

How do you figure out which general partial fraction form you need for a fraction?

Im a female. So shut up.
Aren't you a feisty one.

I literally just told you to simplify it and you will get 4A+B=12 and/or use x=1, 2

Dont assume then. Jane is not a male name, it's an idiotic assumption. I've already got the correct answer. Thanks.

5. With part B, I have this so far

That's what I was actually asking

Why are you so frustrated?

because nobody is looking at my attachment and im stuck

For a general polynomial function of order it is a theorem that for where are polynomial functions of their respective degrees and .

Are you still stuck? I thought you understand now with rdk's help

Please don't post full solutions - the OP would have got there
No he wouldn't have

You call him idiotic then go on to tag him asking for help, really?... lmao

I don't I understand what he wrote.

You've shown in part a that -3 is a root, meaning that (x-3) is a factor of f(x)=0.
Divide f(x) by this using polynomial division (c2 stuff). Then you should have a nice quadratic to factorise. Following that it should be a simple partial fraction question without any of the nasty comparing coefficients needed.
Edit: x+3 not x-3 pardon.
16. RDK already helped you with, gurl, you want 5 people to tell you same thing to get it through your head.

That last one was not for you unless you fully understand the concept of partial fractions which doesn't seem like it at this point.

In regards to your attachment, you have found the left over quadratic when you divided the cubic by . Now factorise that quadratic then express your cubic in terms of 3 the linear factors you end up with.

I didn't call him idiotic, I said his assumption was idiotic. There's a difference , if you weren't too busy flirting with him and RDK
