Answer:You have to apply the well known formula: %28a-b%29%5E2=a%5E2-2ab%2Bb%5E2
Where a=3x and b=2y.
%283x-2y%29%5E2=%283x%29%5E2-2%2A3x%2A2y%2B%282y%29%5E2
%283x-2y%29%5E2=9x%5E2-12xy%2B4y%5E2
Done.

%283x-2y%29%5E2+=+%283x-2y%29%283x-2y%29 Use the FOIL method.
%283x%29%283x%29%2B%283x%29%28-2y%29%2B%28-2y%29%283x%29%2B%28-2y%29%28-2y%29 Simplify.
9x%5E2-12xy%2B4y%5E2
