x^2-25/x divided by x-5/x+2=
type a fraction and leave your answer in factored form

When ever you divide by a fraction you can instead multiply by the reciprocal. 
As what I understand from your question you wrote:
$$[ (x^2 -25)/x ]/ [(x-5)/(x+2)]$$
This changes to:
$$[ (x^2 -25)/x ]*[(x+2)/(x-5)]$$
Now there is something cool we can do... like factor that nasty x^2-25
We should get this when we factor:
$$[ (x-5)(x+5)/x ]*[(x+2)/(x-5)]$$
Which when we multiply across we can see the x-5 cancel out:
$$[(x+5)(x+2)]/x$$
And we are done!

oreostar, try the \frac{numerator}{denominator} macro. Like:$$\frac{\frac{x^2-25}{x}}{\frac{x-5}{x+2}}$$which is written with \frac{\frac{x^2-25}{x}}{\frac{x-5}{x+2}}

Cool, I looked in the equation thing for it and couldn't find a easy button. I will use this in the future. It's so ugly written out the way I did it.
