Quotient rule problem

[skipqtexas]

I'm HAVING TROUBLE SIMPLIFING problems at the last stage. Trying to see if anybody can help.

4x^2/ x^3+3

the becomes 8x^4+24x-12^4

Which when simplified becomes -4x^4+24/x^3+3

How di you et e -4x^4+24?

Also

-3x5/3x+4

Then becomes -9x+12-9x+5/(3x+4)^2

Which the becomes when simplified 27/2x+4 (How did you get that) These are all problems coming from my computer software.

4x^2/ x^3+3

What were the instructions for this expression? What are you supposed to be doing with it?

the becomes 8x^4+24x-12^4

"The" what "becomes" the polynomial expression. How does the polynomial relate to the original rational expression?

Which when simplified becomes -4x^4+24/x^3+3

How does the polynomial "simplify" to get the rational expression?

How di you et e -4x^4+24?

I think you're maybe asking a follow-up question, along the lines of "How did you get (something or other)?" To whom are you speaking? To what previous conversation are you making reference?

-3x5/3x+4

Then becomes -9x+12-9x+5/(3x+4)^2

"Then" what "becomes" this rational expression?

Which the becomes when simplified 27/2x+4 (How did you get that)

"How did" who "get" what?

These are all problems coming from my computer software.

Which are the "these"? Are you saying that you're using some practice software which is generating these exercises? Or are you saying that you're trying to use some "solver" software but that you're having difficulties with it? Or something else?

Please be complete. Thank you!
