Answer 2

Google will have plenty of examples of both.

Answer 3

How could you use Descartes' rule and the Fundamental Theorem of Algebra to predict the number of complex roots to a polynomial as well as find the number of possible positive and negative real roots to a polynomial?

Your response must include:

A summary of Descartes' rule and the Fundamental Theorem of Algebra. This must be in your own words.
Two examples of the process
Provide two polynomials and predict the number of complex roots for each.
You must explain how you found the number of complex roots for each.

Might help

Fundamental theorem of algebra says a poly of degree n has exactly n complexroots.
So because of the fact complex roots come in conjugate pairs, you can determine the nature of the roots you will have particularly if you are aware of how many real roots you have to start with.
