1. function help

I am really bad at this and need help to simplify the following:

(1/2x+8)-(3x/(x+4)^2)+(1/2)

2. Re: function help

Use BODMAS, expand the brackets first.

3. Re: function help

It's starting to come back (I haven't taken math in years and I'm taking a course to upgrade right now), but I am a visual learner so what would help me the most is to actually see the steps then I get a better idea

Hmmm...it's a bit "messy"; are you sure you wrote it down correctly?
Could the (1/2x+8) be 1/(2x+8) instead?

You're right, it is. My mistake.

6. Re: function help

So, is this the exact way the problem is:
Code:
   1         3x      1
~~~~~~ - ~~~~~~~~~ + ~
2x + 8   (x + 4)^2   2
If so, then above then can be re-written this way:
Code:
    1            3x         1
~~~~~~~~ - ~~~~~~~~~~~~~~ + ~
2(x + 4)   (x + 4)(x + 4)   2
