You can put this solution on YOUR website!
You cannot \"solve\" this -- you can, however, factor it.
\n" ); document.write( "If you see:
\n" ); document.write( "\"+x%5E3-27+\"
\n" ); document.write( "This is a \"special case\" because you can rewrite it as:
\n" ); document.write( "\"+x%5E3-3%5E3+\"
\n" ); document.write( "Now, you have a \"difference of cubes\". It should automatically bring to mind:
\n" ); document.write( "\"+a%5E3%96b%5E3+=+%28a+%96+b%29%28a%5E2+%2B+ab+%2B+b%5E2%29+\"
\n" ); document.write( "In your case:
\n" ); document.write( "a is x
\n" ); document.write( "b is 3
\n" ); document.write( "giving you:
\n" ); document.write( "\"+x%5E3-3%5E3+=+%28x-3%29%28x%5E2+%2B+3x+%2B+3%5E2%29+\"
\n" ); document.write( "\"+x%5E3-3%5E3+=+%28x-3%29%28x%5E2+%2B+3x+%2B+9%29+\"\r
