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

Solution

expand

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

Solution

x^{3} - x - 2 x^{2} + 2

Solution steps

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

Expand

(x - 2) (x + 1) (x - 1) : (x - 2) (x^{2} - 1)

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

Apply FOIL method

(x - 2) (x^{2} - 1) : x^{3} - x - 2 x^{2} + 2

= x^{3} - x - 2 x^{2} + 2
