You can put this solution on YOUR website!
%28y-4%29%5E2
You could write it like
(y-4)(y-4)
and then use FOIL. Or you could use the pattern
%28a-b%29%5E2+=+a%5E2+-2ab+%2B+b%5E2
with the "a" being y and the "b" being 4. I like using the pattern:
%28y%29%5E2+-2%28y%29%284%29+%2B+%284%29%5E2
which simplifies to:
y%5E2+-8y+%2B+16
