This is not a question; so I perfectly understand that it could be deleted almost immediately.
Yesterday, I was attending a New Year eve party and I was introduced to a young and brilliant lawyer. Hearing that I am (supposed to be) a mathematician, he seriously told me : "So, could you, by the end, explain to me why is $ax^2+bx+c$ always equal to $0$?".
I took it as a very good joke. The problem is that this was not a joke at all : the guy was serious !!
I am not an educator but I think that there are a lot of questions coming out from it.
I would really appreciate your opinions.
Since questions are required :
what can we do to make better understanding of mathematics starting with young people ?
how can we make mathematics more attractive ?
