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

\n" );
