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

Solution

expand

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

Solution

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

Solution steps

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

Expand

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

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

Apply FOIL method

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

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