How would i solve x^33x^2+2=0?
How would i show it in exact values?

Function 
drwls,
Note that one root is x=1. Call it a lucky guess.
That means that (x1) is a factor of x^33x^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
