This question already has an answer here:
Here is a question A property of the tangent line that I asked where I was confused on the matter "what is the property that characterises a tangent line" and I thought that this property is that the tangent line touches the curve only once, but as has been clarified by the answer ( which is very fine ) to my question that this property is coincidental property due to a deeper property of curves ( Bezout's Theorem ).
All is good and I edited the question, so It became clear what was my confusion. And the answer given does actually answer my question. And still my question gets closed! What is so wrong with my question so it's worthy of getting closed?
