It is difficult to read from where I am, but looks like a simple item.

Can you write it in plain text, i.e, (2x+7)/(x-1) or whatever?

The formatting is not working well and I don't want to guess.

Here is a link to help with La Tex (the built in my type on this site)

http://www.mathhelpforum.com/math-he...-tutorial.html

The code for a fraction is \frac{3}{x-4}-\frac{2}{x^2-16}

To open the math tags click on the sigma (next to the you Tube link). Where I put the above into the math tags I get...

First to find the LCD we want to factor the denominator so we get

Now we notice that the first fraction is missing an x+4 so we build it to get a common denominator

Simplifying we get

Good luck.
