Question

x^3-x^2-x+1 factorisation​

Answer 1

Step-by-step explanation:

${x}^{3} - {x}^{2} - x + 1 \\ = {x}^{2} (x - 1) - 1(x - 1) \\ = (x - 1)( {x}^{2} - 1) \\ = (x - 1)(x - 1)(x + 1)$

Answer 2

$$\begin{lgathered}{x}^{3} - {x}^{2} - x + 1 \\ = {x}^{2} (x - 1) - 1(x - 1) \\ = (x - 1)( {x}^{2} - 1) \\ = (x - 1)(x - 1)(x + 1)\end{lgathered}$$
