x³ - x² + x - 3 (x² + 1)(x - 1) - 2
t3-1/27
(2x - 1)(4x2 + 2x + 1)
(x - 1)(x - 1)(x - 1) - (x + 1)(x + 1)(x + 1)
x(x + 1)(x -1)
(x - 1)(x^2 + x + 1)
8(y - 1)(y^2 + y + 1)
(x + 2)(3x - 1)(3x + 1)
8(y - 1)(y^2 + y + 1)
Factor out the GCF and get X(X2-X+1).
x^3 - x^2 + x - 1 = (x^3 - x^2) + (x - 1) = x^2(x - 1) + (x - 1) = (x -1)(x^2 + 1)
(x - 5)(x^2 + 1)
