$\"%28x%2By%29%5E3=x%5E3%2B3x%5E2y%2B3xy%5E2%2By%5E3=x%5E3%2B3xy%28x%2By%29%2By%5E3\"$
\n" ); document.write( "When $\"x%2By=2\"$ ,
\n" ); document.write( " $\"%28x%2By%29%5E3=2%5E3=8\"$ and

,
\n" ); document.write( "so $\"x%5E3%2B6xy%2By%5E3=8\"$ ---> $\"x%5E3%2B6xy%2By%5E3-8=0\"$ \n" ); document.write( "
