Perform the indicated operation and simplify?
(4x)/(x2)+(8)/(x+2)

Math 
A.P.,
Multiply the first fraction by the denominator of second and vie versa:
4x(x+2)/(x^24)+8(x2)/(x^24)
=(4x^2+8x+8x+16)/(x^24)
You can do a little more from here, but this exerise does not yield a very pretty answer.
Remember that (a^2)(b^2) = (ab)(a+b)

Minor ammendment: I see how the first sentence can be misleading. You multiply both numerator and denominator, not just the numerator.
