Use the distributive property,
%28y%5E2-4%29%284y%5E2-5y%2B4%29=y%5E2%284y%5E2-5y%2B4%29-4%284y%5E2-5y%2B4%29
%28y%5E2-4%29%284y%5E2-5y%2B4%29=%284y%5E4-5y%5E3%2B4y%5E2%29-%2816y%5E2-20y%2B16%29
%28y%5E2-4%29%284y%5E2-5y%2B4%29=4y%5E4-5y%5E3%2B4y%5E2-16y%5E2%2B20y-16%29
highlight%28%28y%5E2-4%29%284y%5E2-5y%2B4%29=4y%5E4-5y%5E3-12y%5E2%2B20y-16%29%29
