What are the step involve in adding and subtracting rational expressions?

I see so you are basically asking for this I suppose?
Simplify into one term:
$$\frac{x+3}{x^{2}-16} + \frac{x}{x+4}$$or$$\frac{x+3}{x+2}\frac{x+6}{x+3}$$if these are the types of question you are looking for, all you have to do is find a common denominator so that you can add the two terms together and cancel out factors. So in the first problem, the common denominator is x^2-16 since:
$$x^2-16 = (x+4)(x-4)$$NOTE:This is called the difference of squares.

In the second problem, you could cancel out the (x+3) factor because it appears in the numerator and denominator. 

NOTE: if you are asked to graph that function it would have a hole at x=-3 due to function ability to cancel out that factor.

Is that your question?
