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

Solution

expand

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

Solution

x^{3} + x^{2} - 4 x - 4

Solution steps

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

Expand

(x - 2) (x + 1) (x + 2) : (x^{2} - 4) (x + 1)

= (x^{2} - 4) (x + 1)

Apply FOIL method

(x^{2} - 4) (x + 1) : x^{3} + x^{2} - 4 x - 4

= x^{3} + x^{2} - 4 x - 4
