Question: For polynomial equations of degree higher than 2 the first thing to do is to look for some grouping of terms that will result in a common factor. For your equation
^{3} - x^{2} + x - 2 = 0
^{3} - 2 - x^{2} + x = 2(x^{3} - 1) - x(x - 1) = 0
^{3} - 1 and simplify.
Another way to approach this problem is with the Factor Theorem. With
^{3} - x^{2} + x - 2
