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

Solution

expand

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

Solution

2 x^{3} - 2 x

Solution steps

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

Expand

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

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

Apply the distributive law:

a (b - c) = ab - a c

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

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

Simplify

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

= 2 x^{3} - 2 x
