Re: polynomials

If a1 is a root, ontain an expression for a1^n using the equation.

Do this for them all and add them up.

Re: polynomials

In mathematics, you don't understand things. You just get used to them.

I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.
