Hi, First, you must develop  the remarkable product (C+D)^2, try

saov · Answer

then, you may assign two numbers for each letter (C and D), and see what is the largest expression, it is the easy way.

saov · Answer

obviosly, C must be greater than D, for example, you can choose C= 8 and D= 4, it is an example. :)
