It's only a quadratic; why can't I do it?I'm stuck on Q1 from You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei #2 20130623 05:54:52
Re: It's only a quadratic; why can't I do it?Hi Bob The limit operator is just an excuse for doing something you know you can't. “It's the subject that nobody knows anything about that we can all talk about!” ― Richard Feynman “Taking a new step, uttering a new word, is what people fear most.” ― Fyodor Dostoyevsky, Crime and Punishment #3 20130623 05:58:33
Re: It's only a quadratic; why can't I do it?Well yes, it does. But surely that can't be it alone. It's a bizarre way to ask that, isn't it? You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei #4 20130623 06:36:09
Re: It's only a quadratic; why can't I do it?I still don't get it. There is no mistake in your proof and your last post there proves that it must be that all three are equal...

Re: It's only a quadratic; why can't I do it?I think the exact wording would help. If a, b and c must be real, then your proof is the whole proof of the result.
