You can put this solution on YOUR website!
If the result is $\"+2k+\"$ then it must be
\n" ); document.write( "true that $\"+%28+2k+%2B+2+%29%2A2k+=+2k%5E2+%2B+4k+\"$
\n" ); document.write( "This is not true, so I don't see how either
\n" ); document.write( "----------------
\n" ); document.write( " $\"+%28+2k%5E2+%2B+4k+%29+%2F+%28+2k+%2B+2+%29+\"$
\n" ); document.write( " $\"+%28+2k%2A%28+k+%2B+2+%29%29+%2F+%28+2%2A%28+k+%2B+1+%29%29+\"$
\n" ); document.write( " $\"+k%2A%28+k+%2B+2+%29+%2F+%28+k+%2B+1+%29+\"$
\n" ); document.write( " $\"+k%2A%28+1+%2B+1%2F%28+k%2B1+%29+%29+\"$
\n" ); document.write( " $\"+k+%2B+k%2F%28+k%2B1+%29+\"$
\n" ); document.write( "This is what I get
\n" ); document.write( " \n" ); document.write( "
