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

Solution

expand

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

Solution

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

Solution steps

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

Expand

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

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

Apply FOIL method

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

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