%28y-3%29%2A%28y%2B5%29I assume the problem looks like this
y%2Ay%2B5%2Ay-3%2Ay-3%2A5The factors FOIL to this
y%5E2%2B5y-3y-15 Multiply each term
y%5E2-2y-15Subtract like terms. This is your answer.


If it looks like this %28y-3%29%2A%28yt%5E5%29 then
%28y-3%29%2A%28yt%5E5%29
%28yt%5E5%29%2Ay%2B%28yt%5E5%29%2A%28-3%29Distribute the %28yt5%29 to every term
y%5E2t%5E5-3yt%5E5This is your answer if the problem looks like %28y-3%29%2A%28yt%5E5%29
Hope this helps.
