You can put this solution on YOUR website!
$\"x%5E2%2B%28y-4%29%5E2=0\"$
\n" ); document.write( "There is only one real solution when both terms on the left hand side equal zero.
\n" ); document.write( " $\"x=0\"$
\n" ); document.write( " $\"y-4=0\"$
\n" ); document.write( " $\"y=4\"$
\n" ); document.write( "So then,
\n" ); document.write( " $\"x%2By=4\"$
\n" ); document.write( " \n" ); document.write( "
