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