We were assigned these problems to do for homework where we're supposed to find the zeros of these equations (cubic, quartic, all those). I did all the synthetic division and all that, did all the stuff, but then got stuck!

So my question is:

Is the Square root of -19, 19i ?

I thought I was right, but someone told me otherwise.
Am I right? If not, can you explain what the correct answer is and how you got it?

Thanks.

Well, for my multivariate calculus math homework, I have to do the proof of this:
lim x->a (u(x)∙v(x)) = lim x->a (u(x)) ∙ lim x->a (v(x))

I have to use the epsilon-delta way to prove it and have no clue where to start.

I need to know how to determine whether each equation is symetric with respec to the x-axis the y-axis the line y=x and the line y= -x.
FOR Y= 1/x^2
If you dont know the formulas they are
x-axis= f(x)= -f(x)
y-axis= f(x)= f(-x)
y=x = (x, f(x) ) <-> ( f(x), x)
y=-x = (x, f(x) ) -> (-f(x), -x)
