Are you going to buy that Math Type package?

:D no I can't afford it but I've been assured by my teachers that the free version works well for what we will be doing.
I'm feeling very discouraged though. I'm not sure I will continue with the course. There is too much that I don't know and my brain is very unreliable. Due to fatigue it's not online most days. When I applied for the course I had just started new medication and was doing really well but it only lasted for a couple of weeks and now I'm back to being dead tired all the time.

Ok I'm done feeling sorry for myself for being completely hopeless and I've done some thinking.
I decided that it doesn't matter that I suck at maths and maybe even fail the course, I'm going to take it anyway. I mean I am learning new things and that was the whole point of taking the course in the first place.
Hopefully I haven't scared of all you math geniuses incase I need to ask more questions! :D

Ask. Just do not ask for the answers to your homework problems.

I wasn't aware that I did. I needed help breaking it down and every step explained (why it's done that way) I apologize if that was wrong!

Aww...you haven't scared me at all. I understand how you feel. Remember, to be a success in life, you need to find out what you love to do, and find a way to make that a career. You're right; not all can be math geniuses (like VectorSpace), but if you find out what you love to do, and make that a career, you will find happiness and be able to spread that to others. I hope you do well in whatever you do.

Thank you! That's very sweet of you!
I have spent many years trying to figure out what my greatest love/interests are. I still don't know but I love technology, computers, art and writing. Anyhow I think mechanical engineering would be great! I would get to invent stuff and also design stuff.
However I would need to be great at maths to become an engineer which is not likely to ever happen but I figured I'd give it a shot.

I don't think you did anything bad. OK, you were given the solution, but you wanted to understand it.

Well I have no interest in just getting the answer, I need and want to learn this stuff! I'm still hoping that my total cluelessness is just that, ignorant. There is still this glimmer of hope somewhere at the back of my head that thinks I might just be good at this stuff if I just learned it.

Ok I'm working on a third grade equation now. I know this is probably a long shot but, could I not just make it a second or ordinary equation and solve it like that?

That sometimes works. If you already know one zero, you can do polynomial division and obtain a 2nd degree polynomial. But the approach to chose really depends on the equation.

Ok so if I already have a one zero and make it into a 2nd degree then I will still end up with three roots right? Do I always need to account for all the roots and does it matter in which order?

In the "good" case, a 3rd degree polynomial has 3 real roots. But I think you should just post the problem here.

Order doesn't matter.

You'll always get 3 roots with a 3rd degree equation, but sometimes you get a multiple root, and sometimes the roots are complex numbers. (An example of a multiple root: (x-1)(x-1) = x^2 - 2x + 1 = 0. x = 1 is the only solution, but the factor (x-1) shows up twice when you factor it.)
