**drwls**, Saturday, January 9, 2010 at 7:23pmHave you learned about synthetic (or polynomial) division?

If not, you should. The following reference should help.

One of the roots of P(x) = 0 will be x = -1, since x+1 is a factor. To get the other three roots, you need to solve the cubic equation

2x^3 -3x^2 +16x -24 = 0

That will not be easy.

You will find some hints here:
