Distributive property of the cross product

Prove the following?

Vectors
(v-w)x(v+w)=2(vxw)

 

[Defennder]

Just use the distributive property of the cross product.

So I am guessing if you have VxV and WxW they are both equal to 0

Why do you have to guess that? What's the cross-product of two parallel vectors?

Yes.
