Ok lets give it a try..This isn't just synthetic division tho.. it uses it but its not only synthetic division.
Find all zero's of each of the following polynomials.
f(x)=6x^3 - x^2 - 13x +8
thats easy if you can use a graphing calc. Type the equation into and then go to graph. You know there is 3 zeros because the highest x power is to the 3rd. After you put it in go to the calc button above the trace key and select zeros. Then set the left boundary and right. The boundries will be the two sides of the line where it crosses the x axis.
so they are:
X=-1.644243
x=.81090999
x=1
For that equation the zoom box helps alot to get close in on it.
