f(x) = x^3 - 12x^2 + 36x - 32; 8
Given a polynomial function and a zero, find the other zeros.
------
Use synthetic division with the given root:
8)....1....-12....36....-32
......1.....-4....4...|..0
-----
Find the zeroes of the quadratic dividend:
Solve x^2 -4x + 4 = 0
(x-2)^2= 0
Roots are 2, and 2
----
All the Roots are 8,2,2
