Can anyone explain these to me ? I'm clueless as to how to do these.

Factor Theorem

Use the Factor Theorem to show that x - c is a factor of P(x) for the given value(s) of c.

P(x) - x^3 - 3x^2 + 3x - 1, c = 1

Also i'm having problems with a type of question that I also don't know where to start.

Find a polynomial of the specified degree that has the given zeros.

Degree 3; Zeros -1 , 1, 3

HELP!!!
