## Homework Statement

x^3-8x+10=0

## Homework Equations

## The Attempt at a Solution

By dividing by x-1 (1 is a factor of the solution), I got (x-1)(x

^{2}+x-7)+3+10=0

which equals x^3-8x+20=0

I think the solution would be imaginary but I used a graphing calculator and there is one solution but I don't know how to calculate it.
