Hi all,
I'm currently flicking through and old textbook and came across the following.

"Every polynomial of the form

, where

has n linear factors over C...". What does it mean by [URL]http://latex.codecogs.com/gif.latex?a^{n}\neq0?[/URL] Is this referring to some kind of complex index? This is all that is written and nothing precedes it. I just don't quite understand the

.Edit: Latex kind of fixed

Hi SprucerMoose!

(try using the X² and X₂ icons just above the Reply box )

it must be a misprint for "where a₀ ≠ 0" …

Ah, I see. Thank you very much.Testing...

a² + a₀ + a₁

Edit: It works!

Now you really are sprucer!

a² + a₀ + a₁

Do you mean a₂ + a₀ + a₁?

 

[SprucerMoose]

Do you mean a₂ + a₀ + a₁?

Do you mean a² + a⁰ + a¹?
