comment Can you show why zero divided by zero does not equal zero?
@DonAntonio Yes, sorry I do not necessarily mean prove. I asked that since everything seems to revolve around proofs for me recently. I realize it is undefined. Perhaps show that it does not work is what I am interested in.

comment Is it more practice and intuition or rather algorithmic to solve third degree polynomials of this type?
My brain does not work like yours, but I hope it starts to soon.

Luckily this is a nice equation, thank you I have at least one extra tool in my belt and I will need to read up more on the rational root theorem among other things. Your answer is very clear and concise.

Yes, sorry forgot to square that one.

I kind of get what you and Will Jagy are saying, but it will take time to absorb. The only thing that is immediately obvious from your last equations is that c = 6. I appreciate your helps.

accepted The author of my book simplifies his solutions to an extent that I am uncomfortable with, so are my solutions to homework over doing it?

@amWhy Hopefully its complete and valid, for reals this time.

Thank you, this will take some getting used to but I think I am seeing the logic better, I should probably delete the previous comments though to save space.
