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

Solution

expand

x (x + 2) (x - 2)

Solution

x^{3} - 4 x

Solution steps

x (x + 2) (x - 2)

Expand

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

= x (x^{2} - 4)

Apply the distributive law:

a (b - c) = ab - a c

x (x^{2} - 4) = x x^{2} - x \cdot 4

= x x^{2} - x \cdot 4

Simplify

x x^{2} - x \cdot 4 : x^{3} - 4 x

= x^{3} - 4 x
