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

Solution

expand

x (x + 1) (x - 2)

Solution

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

Solution steps

x (x + 1) (x - 2)

Expand

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

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

Apply the distributive law:

m (a + b + c) = ma + mb + m c

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

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

Simplify

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

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