Question

x³-2x²-x+2 factor the polinomial as the product of three binomial​

Answer 1

${x}^{2} (x - 2) - 1(x - 2) = 0$

$( {x }^{2} - 1)(x - 2) = 0$

$x = 2$

$x = - 1$

$x = 1$

Answer 2

Answer:

(x+1)(x-1)(x-2)

Step-by-step explanation:

x^3-x-2x^2+2

= x(x^2-1)-2(x^2-1)

=(x^2-1) (x-2)

= (x+1)(x-1)(x-2)
