How would i show it in exact values?

**drwls**, Tuesday, July 22, 2008 at 11:06pmNote that one root is x=1. Call it a lucky guess.

That means that (x-1) is a factor of x^3-3x^2+2.

Use long division to get the other factor: x^2 -2x -2

That factors into (x - 1 -sqrt3) and (x - 1 + sqrt3)

That should tell you all three roots:

1, 1 + sqrt 3 and 1 - sqrt 3
