Which is not a factor of x³ - x² - 2x ?

A.) x

B.) x + 1

C.) x - 1

D.) x - 2

A.) x

B.) x + 1

C.) x - 1

D.) x - 2

x³ - x² - 2x

= x(x² - x - 2) {factored x out}

= x(x - 2)(x + 1) {factored into two binomials}

= x(x² - x - 2) {factored x out}

= x(x - 2)(x + 1) {factored into two binomials}

**C.) x - 1**is not a factor
