To happy...
Yes I did happy. The problem is I decided to take this course online (I have an infant at home and couldn't really get away three days a week). To be honest, the only imaginary number I understand is the one I hope to get in this class, which is a 70%!

There is a growing group of mathematicians who do not like the term “imaginary numbers”. It is an accident history just like the term “random variable” so we may be stuck with it. Many new treatments of complex variable start by stating that i is an artificial (made up) ‘number’ that is added to the real field and is a solution of the equation x<SUP>2</SUP>+1=0.
If it is made-up, ponder why this little gem is true: \(\displaystyle e^{i\pi } + 1 = 0\) where \(\displaystyle \ln (e) = 1\).

3*x<sup>2</sup> + 1*x + 2 = 3*x<sup>2</sup> + x + 2
It's just a convention. Don't let it trouble you. One normally would not write a coefficient of 1.
3*x<sup>2</sup> + 0*x + 2 = 3*x<sup>2</sup> + 0 + 2 = 3*x<sup>2</sup> + 2
It's just a convention. Don't let it trouble you. One normally would not write the whole term if the coefficient is 0.
3*x<sup>1</sup> = 3*x
It's just a convention. Don't let it trouble you. One normally would not write an exponent of 1.
There are many conventions. Just learn to recognize them and use them.
Think of them as "it goes without saying". It really does!
