Find the zeros of the polynomial function P(x)=x^3-x^2-2x+2 and the multiplicity of each.
---------
The coefficients add to zero so x=1 is a zero of P(x)
--------------
Then use synthetic division to help find the other zeroes:
1)....1....-1....-2....2
........1.....0....-2..|..0
============
Remainder: 0
Quotient: x^2-2
---------------
Find the zeroes of the Quotient factor:
x^2-2=0
x=sqrt2 or x=-sqrt2
