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

Solution

expand

x (x + 1) (x - 1)

Solution

x^{3} - x

Solution steps

x (x + 1) (x - 1)

Expand

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

= x (x^{2} - 1)

Apply the distributive law:

a (b - c) = ab - a c

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

= x x^{2} - x \cdot 1

Simplify

x x^{2} - x \cdot 1 : x^{3} - x

= x^{3} - x
