1 - x3 = (1 - x)(1 + x + x2) So the roots are 1 (the root of 1 - x) and [-1 +/- sqrt(-3)]/2 (the roots of x2 + x + 1, via the quadratic formula. Note: Sqrt means "square root", and +/- means "plus-or-minus". This site has no easy access to those symbols.

What is x minus 1 cubed?
xcubed-1 Answer::(X-1)(Xsquared+X+1) when you factor xcubed minus a number its the same thing as x cubed minus y cubed and x cubed minus y cubed factors to:: (x-y)(xsquared+xy+y squared) the first factor, (x-y), is the cubed root of the first and the cubed root of the second, so in the answer i have (x-1), which is x cubed minus one cubed :) the second factor, (xsquared+xy+ysquared), you take the first number squared, Xsquared, then the first and second one multiplied together, XY, and then the second number squared, Ysquared, so in the answer i have (xsquared+x+1), which is x squared, then x times 1 which is just x, and positive 1, which is negative 1 squared :) x^3 - 1
