You can put this solution on YOUR website!
You are almost there. You are probably getting
\n" ); document.write( " $\"6r%5E2+=+85\"$
\n" ); document.write( " $\"r%5E2+=+85%2F6\"$
\n" ); document.write( " $\"r+=+sqrt%2885%2F6%29\"$
\n" ); document.write( "But your answer needs to be rationalized (it should not have a square root in its denominator
\n" ); document.write( " $\"r+=+sqrt%2885%2F6%29+%2A+sqrt%286%2F6%29\"$
\n" ); document.write( " $\"r+=+sqrt%28510%29+%2F+6+\"$ \n" ); document.write( "

\n" );
