(4x)/(x-2)+(8)/(x+2)

**A.P.**, Monday, March 26, 2012 at 10:23amMultiply the first fraction by the denominator of second and vie versa:

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

=(4x^2+8x+8x+16)/(x^2-4)

You can do a little more from here, but this exerise does not yield a very pretty answer.

Remember that (a^2)-(b^2) = (a-b)(a+b)
