This is a problem of factorization.
Use the identity : a2 - b2 = ( a + b) ( a - b)
here a2 equals 4X2 , and b2 equals 4y2
Then :
4 X2 - 4Y2 = ( 2X +2Y) ( 2X - 2y)

Hi Jerry,
There must be more to this problem. Was there anything on the right side of the equal sign? What were the instructions for that section of problems? Were you supposed to factor the problem maybe? Give us a little more detail and one of us will be happy to help.
