You can put this solution on YOUR website!
$\"sqrt%282y+%2B+7%29+%2B+4+=+y\"$
\n" ); document.write( " $\"sqrt%282y+%2B+7%29+=+y+-+4\"$
\n" ); document.write( " $\"2y+%2B+7+=+%28y+-+4%29%5E2\"$
\n" ); document.write( " $\"2y+%2B+7+=+y%5E2+-+8y+%2B+16\"$
\n" ); document.write( " $\"0+=+y%5E2+-+10y+%2B+9\"$
\n" ); document.write( " $\"0+=+%28y+-+9%29%28y+-+1%29\"$
\n" ); document.write( "y = 9 and y = 1
\n" ); document.write( "y = 1 doesn't work ... y = 9 is the only answer \n" ); document.write( "
