## LCD Question

I am trying to figure out how to find the lowest common denominator when the denominator has addition in it. I would really like to see this one worked out. Here is the problem, and the answer the book gave:

(5/(2x+4)) + (3/(x+2)) = 2

answer was 3/4

What was the LCD I should multiply by?

Thanks!
