%285a-3b%29%5E2=%285a%2B%28-3b%29%29%285a%2B%28-3b%29%29
Use the FOIL method (First, Outer, Inner, Last)
%28highlight%285a%29%2B%28-3b%29%29%28highlight%285a%29%2B%28-3b%29%29First : %285a%29%285a%29
%28highlight%285a%29%2B%28-3b%29%29%285a%2Bhighlight%28-3b%29%29Outer : %285a%29%28-3b%29
%28%285a%29%2Bhighlight%28-3b%29%29%28highlight%285a%29%2B%28-3b%29%29Inner : %28-3b%29%285a%29
%28%285a%29%2Bhighlight%28-3b%29%29%28%285a%29%2Bhighlight%28-3b%29%29Last : %28-3b%29%28-3b%29

%285a-3b%29%5E2=25a%5E2-15ab-15a%2B9b%5E2
%285a-3b%29%5E2=25a%5E2-30ab%2B9b%5E2
