Because I can't write squared, if x is squared, I will just write it like this: xsquared
x/x +2 MINUS x/xsquared  4 = x+3/x+2 I get an LCD for each fracton and then I subtract getting this: xsquared  2x MINUS x/xsquared  4 = (x+3)(x2)/xsquared  4 What do I do now? If you don't understand this just ask me to scan it

I suppose you mean
[tex] \frac{x}{x+2}  \frac{x}{x^24} = \frac{x+3}{x+2} \Longrightarrow \frac{x^2  3x}{x^2  4} = \frac{(x+3)(x2)}{x^2  4}[/tex] which is fine.

I'm not quite sure what you mean. I surmise it is something like this: [tex] \frac{x}{x+2}\frac{x}{x^24}=\frac{x+3}{x+2}[/tex] If it's not right, let me know. EDIT: Yarr, Data got there before I did...

Fractional Equations
And that is where I got but the instructions are to solve Is that a solution to it?

Note that there is a small error in the thing you quoted, which I've corrected now.
To solve, multiply [itex]x^24[/itex] through both sides, expand on the right, and see what you get.

This is what I'm getting: xsquared  2x  x = xsquared + x  6 I subtract xsquared on each side to cancel them out getting: 2x  x = x  6 I then subract x from each side getting 3x  x = 6 Then I subract the x 4x = 6 Did I mess up?
